Wiser Merchant's threshold-based discounts apply only when the qualifying subtotal reaches the stated minimum. The lower threshold provides a percentage reduction on the order subtotal, while the higher threshold provides a fixed-dollar reduction, so an order below either threshold will not qualify.

The threshold is generally evaluated against the merchandise subtotal, not necessarily the final amount shown at checkout. Shipping, taxes, gift certificates, and other non-product charges may not help satisfy the requirement. Wiser Merchant's homepage describes separate offers for orders over $100 and over $800.

To troubleshoot:

1. Review the cart subtotal before shipping and tax.
2. Remove excluded or non-qualifying items if the offer terms identify them.
3. Confirm that the discount's minimum is reached by eligible merchandise alone.
4. Reapply the discount after changing the cart.
5. If the threshold is met but the discount still fails, check whether another promotion is already applied or contact Wiser Merchant support.

Wiser Merchant checkout appears to process discounts on a one-code-at-a-time basis. Applying a threshold discount together with a first-order offer, category promotion, or buy-one-get-one promotion may cause one offer to replace the other or produce an invalid-coupon message.

Wiser Merchant uses a "Coupon/Gift Certificate" or "Add Coupon" field during cart or checkout processing. Because the field is designed to validate a discount source against the current order, stacking two ordinary coupons is not reliably supported. Third-party coupon listings also describe the offers as alternatives rather than cumulative discounts, though that evidence is lower confidence than Wiser Merchant's own checkout presentation.

For the cleanest test:

1. Remove the currently applied discount.
2. Verify that the cart satisfies the selected offer's threshold or category conditions.
3. Apply only that discount.
4. Refresh the order summary and confirm that the price changed.
5. If it fails, test the other offer separately rather than combining them.

Wiser Merchant discounts are not necessarily universal across every product category. The catalog covers health and beauty, skincare, nutrition, vitamins, minerals, supplements, medicine-cabinet products, and related sections, while some promotions are described as category-specific.

A percentage discount attached to a broad order threshold may apply to eligible merchandise across the store, but a supplement promotion or health-and-beauty offer may exclude skincare, medicine, household, or other categories. The product category alone is not enough to establish eligibility because individual items may also be excluded.

To identify the cause of a rejection:

1. Check the offer's stated category and exclusions.
2. Test the discount with only products from the named category.
3. Compare the result with a mixed-category cart.
4. Confirm that the cart still meets any required subtotal.
5. If the discount works only after removing unrelated products, the promotion is likely category-limited rather than storewide.

Wiser Merchant's category structure makes this single-category test especially useful when a mixed cart contains supplements alongside skincare or other health products.

A Wiser Merchant discount may fail because it is expired, limited to a first purchase, restricted to eligible products, below its required subtotal, or already redeemed. Public listings mention first-order offers, though available evidence does not establish a universal expiration, account-use, or redemption policy for every Wiser Merchant promotion.

Check the offer in this order:

1. Confirm that the promotion is still displayed by Wiser Merchant or is recently verified by a reliable tracking source.
2. Check whether the terms say first order, new customer, single use, or account-specific.
3. Sign out and compare the cart with the account signed in, if the offer is described as a new-customer promotion.
4. Verify the required subtotal and eligible categories.
5. Apply the discount once and inspect the order summary for an explicit acceptance or rejection message.

If a first-order discount worked previously, it may be tied to the customer account, email address, payment details, or delivery information. Wiser Merchant support can confirm whether the account has already redeemed an account-limited promotion.
