Why won't ACART10 or Mem25 apply at C8 Nail Supply checkout even though I spent over $100?

ACART10 ($10 off $100+) and Mem25 (25% off) won't apply together because C8 Nail Supply allows only one promo code per order, and they may have expired by now. Users often see "Invalid code" or "Promo code not applicable" errors when trying both, as the system rejects multiple codes or checks minimums strictly during checkout. ACART10 requires exactly $100+ pre-discount subtotal (excludes taxes/shipping), while Mem25 is percentage-based and may exclude sale items. A common scenario is when your cart hits $100 after discounts, triggering failure. Step-by-step fix: 1. Remove all codes, add items to reach $100+ subtotal 2. Enter one code (try ACART10 first) in the "Promo Code" field at checkout 3. Click "Apply"—discount shows if valid; if not, clear cache or try incognito Limitations include codes expiring quickly, no stacking allowed, and free shipping only on $200+ orders. Pro tip: Test codes on a small $100 cart first to confirm before placing big orders.

What's the exact minimum order for C8 Nail Supply promo codes like $10 off $100 or $50 off $500, and why does it say invalid?

Minimums are $100 pre-tax/subtotal for $10 off (ACART10) and $500+ for $50 off (Mem50), showing "invalid" if subtotal is lower, code expired, or applied to sale/excluded items. Real-user reports note errors like "Order total does not meet minimum" when shipping pushes past but subtotal doesn't qualify. C8 enforces strict pre-discount checks at checkout to prevent abuse. Step-by-step solution: 1. Build cart to exact minimum (e.g., $100 subtotal, no discounts yet) 2. Proceed to checkout, paste code in "Promo Code" box 3. Apply—watch for updated total; add items if needed Restrictions include one code per order and exclusion of prior purchases. Codes often fail on bundled items. Pro tip: Screenshot cart subtotal before applying to verify against code terms.

How do I stack promo codes with C8 Coins rewards at C8 Nail Supply during checkout?

You can't stack promo codes with each other, but C8 Coins (rewards points) apply automatically after promo codes at checkout—no manual entry needed. Members earn 5 Coins/$1 spent, redeemable as $1 off (200 Coins = $1), but users report "Rewards not applying" if not logged in or subtotal too low. Promo discount hits first, then Coins on final total. Step-by-step: 1. Log in to account (sign up for 200 starter Coins) 2. Add items, apply one promo code at checkout 3. Coins deduct automatically from "Rewards" section if balance covers Coins from referrals, Instagram, and birthday promotions add instantly; free shipping is available on orders $200+. Pro tip: Redeem Coins on $200+ orders for free shipping synergy.

Promo code not working at C8 Nail Supply – is it expired or do I need to be a member first?

Promo codes fail most often from expiration or invalid cart—not membership, as codes work for all but members get extras like Coins. Common errors: "Code expired" or "Does not apply," seen in user tests when past date or under minimum ($100+ for most). No membership is required for basic codes. Step-by-step troubleshoot: 1. Check code expiry on coupon sites 2. Log in/out, clear cart, re-add items to $100+ subtotal 3. Paste in "Promo Code" field, apply—if fails, try alternate like ACOUT10 Limitations include one code per order and no post-checkout additions. Pro tip: Join rewards for automatic Coins and test codes mid-checkout before payment.
