A checkout can accept a promo code and still make your order more expensive. That sounds odd until you see what happened: the code knocked $8 off your items but removed a $10 shipping discount.
Coupon stacking means using more than one promotion in the same order. The trick is to check which discounts survived after you applied the code.
Look at what is already applied
Start with the cart as it is. Note the item prices, any automatic discount, the delivery charge, and the final total. An item marked down on its product page and an offer applied at checkout may be treated differently by the store.
Read the code terms for phrases like “full-price items only,” “one code per order,” or “cannot be combined with other offers.” A first-order code may also require signing in with an eligible account. For help diagnosing a rejected offer, see our guide to why coupon codes don’t work.
Test each offer on the same cart
Apply one code and look at the order summary. Did the subtotal drop? Did a free delivery line disappear? Did a gift or another discount come off the order?
Imagine your cart starts at $80 with free delivery. You enter a 10% code and the subtotal falls to $72. Delivery now costs $10, making the new total $82 before tax. The original cart was cheaper by $2.
If a retailer allows more than one code, try the combination without changing the items or delivery address. If it only allows one, compare the available codes individually. Write down the totals if the checkout makes it hard to switch back and forth.
Check the free shipping threshold
Suppose free delivery starts at $75. Your basket is $79, but a code brings it to $71. If the store calculates eligibility after the discount, a delivery fee may appear. Another store may calculate the threshold differently, so read its terms and use the final order summary as your check.
Check regular store offers separately
A store page can list everyday offers during Black Friday weekend. Check the offer wording and terms before treating it as a Black Friday deal or trying to combine it with another discount.
These links are regular CouponNight store listings. Check the retailer’s terms for product eligibility, shipping charges, and any offer that appears at checkout.
Canada Shrooms: If you came across a shrooms chocolate bar while browsing, see the Canada Shrooms store listing.
BPS Knives: If you’re comparing kitchen knives, see the BPS Knives store listing.

Frequently Asked Questions
Does a sale price count as a coupon?
Not necessarily. A sale price can be built into the item price, while a coupon is applied separately. Whether they can be combined depends on the retailer’s promotion terms.
Is an accepted code always the best offer?
No. It can replace a more valuable discount or change your shipping cost. Check the final total before placing the order.
How can I tell if a coupon is a Black Friday offer?
Look for Black Friday wording, eligible products, and valid dates in the retailer’s terms. A regular coupon can still work during the sale weekend if you meet its conditions.
