OAS Company Promo Codes & Coupons February 2026

Your OAS Company promo code might show "invalid code" for several reasons, even if it appears to be current. Common issues include the code reaching its usage limit, being part of a flash sale that ended early, or coming from an unofficial third-party site not recognized by OAS Company.

To troubleshoot your invalid code issue:

1. Double-check that you're copying and pasting the exact code with correct capitalization
2. Clear your cart, re-add your items, and try applying the code again
3. Try using a different browser or incognito mode to avoid cookie-related issues
4. Verify the code hasn't expired (many codes only last 24-48 hours)

Pro tip: Always verify promo codes directly on the official OAS Company website before checkout to ensure they're still active and applicable to your purchase.

To apply a 20% off code like EXTRA20 or WELCOME20 on OAS Company's website:

1. Add your desired items to your shopping cart
2. Proceed to checkout
3. Look for the promo code or coupon field in the order summary section
4. Enter your code exactly as shown (including correct capitalization)
5. Click "Apply" to see the discount reflected in your total

Note that these codes typically work site-wide but may exclude certain items like gift cards or products already on sale. The discount will appear immediately after applying if the code is valid.

Pro tip: Apply your promo code before calculating shipping, as some discounts may stack with free shipping offers (typically available on orders over $150).

Yes, OAS Company promo codes are case-sensitive. You must enter the code exactly as shown, including correct capitalization. For example, "WELCOME20" in all caps will work, but "welcome20" in lowercase will trigger an "invalid code" error.

This is standard practice for many e-commerce sites, and there are no workarounds. Always copy the code exactly as displayed from official sources.

Pro tip: Triple-check the capitalization of your promo code before applying it at checkout to avoid unnecessary frustration.

Yes, OAS Company offers first-order discounts, typically ranging from 15-20% off with codes like NEW15 or WELCOME20. These codes are often tied to newsletter sign-ups and are designed specifically for new customers making their first purchase.

These first-order discounts usually apply to regular-priced items but may exclude sale merchandise. The codes typically have expiration dates, so it's best to use them promptly.

Pro tip: Sign up for the OAS Company newsletter before making your first purchase to receive a welcome discount code directly to your inbox.

OAS Company discount codes typically don't work on sale items because the company prevents "stacking" discounts. When you try to apply a code like 20% off to already discounted merchandise, you'll receive a "code not applicable" error.

This is a common retail policy to prevent multiple discounts on the same items. To use your promo code, you'll need to shop for full-priced merchandise instead.

Pro tip: Filter for "full price" items on the OAS Company website before shopping if you plan to use a promo code to avoid disappointment at checkout.

No, OAS Company only allows one promo code per order. If you attempt to apply multiple codes, only the last one entered will be applied, overriding any previous codes. This is a standard limitation in their checkout system.

When deciding which code to use, prioritize the one that offers the highest value for your specific order.

Pro tip: If your order qualifies for free shipping (typically on orders over $150), this benefit will apply automatically without requiring a separate code, allowing you to use your discount code instead.

OAS Company student discount codes (typically available through verification services like UNiDAYS) apply to most full-priced items but have several exclusions. These codes generally don't work on sale items, gift cards, or select swimwear collections.

To use a student discount, you'll need to verify your student status through the appropriate platform and then apply the code at checkout for 10-15% off eligible items.

Pro tip: For maximum savings, focus on full-priced activewear and regular merchandise when using student discounts, as these items are most likely to be eligible.

OAS Company promo codes typically remain valid for 1-7 days, though some may last longer for seasonal promotions. Many codes also have usage limits (for example, valid for the first 100-1000 customers), which can cause them to expire before their official end date.

Flash sale codes often have the shortest durations and may deactivate mid-promotion if they reach their usage cap.

Pro tip: Use promo codes as soon as you find them, especially during high-traffic shopping periods when codes are more likely to reach their usage limits quickly.

Your OAS Company discount might be removed at the final checkout step if inventory status changed, taxes were recalculated, or the promo code reached its usage limit between adding it to your cart and completing payment.

To resolve this issue:

1. Go back to your cart
2. Refresh the page
3. Reapply your promo code before proceeding to shipping information
4. Complete checkout without further modifications to your order

Pro tip: Once you've applied a valid promo code, try to complete your purchase promptly without making additional changes to your cart to avoid losing the discount.

Yes, OAS Company free shipping codes typically come with several restrictions:

1. Orders must meet a minimum threshold (usually $150+ USD)
2. Shipping to PO boxes is often excluded
3. Expedited or express shipping options are generally not eligible
4. International shipping may have different requirements

Free shipping offers usually apply to standard shipping within the US and can often be combined with percentage-off discounts on full-priced items.

Pro tip: If you're close to the free shipping threshold, consider adding one more item to your cart to qualify and save on shipping costs.

OAS Company promo codes work internationally in countries where shipping is available, but with limitations. Some codes like WELCOME20 may be restricted to US billing addresses, and international customers should be aware that duties and taxes are not covered by discounts.

Success rates vary by region, with some users reporting issues when using non-US payment methods or shipping addresses.

Pro tip: Enter your shipping address early in the checkout process to confirm whether your promo code will apply to your international order before proceeding to payment.

OAS Company discount codes often target specific product categories. For example, a code like EXTRA20 might apply to outerwear or tops but exclude swimwear, sale items, or gift cards according to the promotion's terms.

When you apply such a code at checkout, you'll notice it only discounts eligible items in your cart, resulting in a partial discount if your order contains a mix of eligible and ineligible products.

Pro tip: Before finalizing your purchase, review which items received the discount in your cart summary to ensure you understand how the promo code is being applied to your specific order.
