CODE ACTIVE TIME PASSES CODE DISABLED Displayed end date passed Limited inventory / promotion ended Retailer disabled the code early Old code still appears on third-party pages Timezone difference RECENT EVIDENCE MATTERS. RETAILER CHECKOUT IS THE FINAL AUTHORITY. PROMIZI | 2026 SHOPPER GUIDE 04
5. PROMO CODE MINIMUM SPEND #2 - YOU HAVEN'T REACHED THE MINIMUM SPEND ILLUSTRATIVE EXAMPLE PROMO ELIGIBLE SUBTOTAL $20 OFF $100+ Cart subtotal $94 ADD ITEM +$8 $102 WHAT MAY NOT COUNT? SHIPPING TAX Threshold reached GIFT CARDS CODE REJECTED CONDITION NOW MET EXCLUDED ITEMS Retailer terms vary. Qualifying subtotal rules are not universal. CHECK THE QUALIFYING SUBTOTAL - NOT JUST THE CART TOTAL. PROMIZI | 2026 SHOPPER GUIDE 05
6. NEW CUSTOMER PROMO CODE #3 - NEW CUSTOMERS ONLY RETAILER RULES VARY RETURNING CUSTOMER NEW CUSTOMER 15% OFF YOUR FIRST ORDER 15% OFF YOUR FIRST ORDER A RETAILER MAY DEFINE "NEW" USING: Account history Email or phone Shipping details Payment details NOT ELIGIBLE POTENTIALLY ELIGIBLE Other criteria Not every retailer checks every signal. "FIRST ORDER" IS AN ELIGIBILITY RULE, NOT JUST A MARKETING PHRASE. PROMIZI | 2026 SHOPPER GUIDE 06
7. PROMO CODE EXCLUSIONS #4 & #5 - PRODUCT AND SALE-ITEM EXCLUSIONS ILLUSTRATIVE EXAMPLE CART T-shirt $30 "20% OFF" ELIGIBLE does not necessarily mean Shoes $80 EXCLUDED BRAND Sale jacket $50 SALE ITEM EXCLUDED 20% × $160 Possible eligible discount 20% × $30 = $6 TOTAL CART $160 ELIGIBLE SUBTOTAL $30 THE HEADLINE DISCOUNT MAY APPLY TO ONLY PART OF THE CART.

10. COUPON STACKING #9 - ANOTHER PROMOTION BLOCKS STACKING ILLUSTRATIVE STACKING EXAMPLE 20% OFF SALE + 10% PROMO CODE IF SEQUENTIAL DISCOUNTS ARE ALLOWED 20% OFF CAN THESE STACK? $100 10% OFF $80 STACKING ALLOWED TOTAL REDUCTION BEST OFFER ONLY 28% $72 NOT 30% ONE PROMO CODE ONLY Stacking rules vary by retailer and discount type. DO NOT ASSUME TWO PERCENTAGES SIMPLY ADD TOGETHER. PROMIZI | 2026 SHOPPER GUIDE 10
11. PROMO CODE DISCOUNT CAP #10 - THE DISCOUNT HAS A CAP ILLUSTRATIVE EXAMPLE PROMO HEADLINE CALCULATION 20% OFF 20% of $200 = $40 CAP APPLIES MAXIMUM DISCOUNT $25 Cart $200 ACTUAL MAXIMUM FINAL ELIGIBLE DISCOUNT $25 $25 "20% off" can be technically correct even when the benefit is capped. ALWAYS READ MAXIMUM-DISCOUNT LANGUAGE. PROMIZI | 2026 SHOPPER GUIDE 11
12. TIME-SENSITIVE OFFER TERMS #11 - THE CONDITIONS CHANGED Retailers can change an offer while it is live. That does not mean every retailer does. MONDAY WEDNESDAY FRIDAY 20% off selected items Same code 10% off / narrower selection Disabled WHAT CAN CHANGE? ELIGIBLE PRODUCTS DISCOUNT AMOUNT MINIMUM SPEND CUSTOMER ELIGIBILITY END DATE STACKING RULES COUPON INFORMATION IS TIME-SENSITIVE. PROMIZI | 2026 SHOPPER GUIDE 12
13. PROMO CODE TECHNICAL ERROR #12 - THE CHECKOUT ITSELF FAILED A failed attempt does not always prove the promotion itself is invalid. 01 CODE FIELD ERROR 02 SESSION EXPIRED 03 CART REFRESHED 04 DISCOUNT DISAPPEARED 05 MOBILE / DESKTOP DIFFERENCE 06 RETAILER ERROR MESSAGE TRY THIS REFRESH CART CONFIRM REGIONAL SITE SIGN IN IF REQUIRED RE-ADD ELIGIBLE ITEMS RE-ENTER CODE EXACTLY READ RETAILER ERROR Troubleshoot the checkout - never bypass retailer restrictions. READ THE RETAILER ERROR MESSAGE BEFORE ABANDONING THE PURCHASE. PROMIZI | 2026 SHOPPER GUIDE 13
14. VERIFIED COUPON NOT WORKING WHY A VERIFIED CODE CAN STILL FAIL FOR YOU WHAT VERIFICATION CAN TELL YOU WHAT IT CANNOT GUARANTEE Your cart qualifies Recent evidence exists Your account qualifies Someone or something checked it Your region qualifies Successful use may have been observed The retailer has not changed conditions Offer information may be current Every shopper gets identical results VERIFICATION IS EVIDENCE - NOT A GUARANTEE. PROMIZI | 2026 SHOPPER GUIDE 14
15. SHOPPER COUPON FEEDBACK WHY SHOPPER FEEDBACK MATTERS SHOPPER A SHOPPER B SHOPPER C SHOPPER D WORKED FAILED WORKED FAILED PROMIZI When available, shoppers can report whether a promo code worked using Yes / No feedback. RECENT OUTCOME SIGNAL Those reports can influence success information and code ordering according to the current Promizi process. SEE HOW PROMIZI WORKS Repeated recent feedback can help distinguish broadly working, restricted, deteriorating and apparently dead codes. FRESH, REPEATED OUTCOMES ARE MORE USEFUL THAN A STATIC "WORKS" LABEL. PROMIZI | 2026 SHOPPER GUIDE 15
16. PROMO CODE VS LIVE DEAL PROMO CODE OR LIVE DEAL? THEY ARE NOT THE SAME THING PROMO CODE LIVE DEAL SAVE20 30% off selected shoes Shopper copies the code and enters it at checkout. Shopper follows the retailer offer. No code may be required. Copy code Open retailer offer Enter at checkout May require no code Discount depends on code eligibility Discount may already be reflected Promizi separates these offer types. BROWSE CURRENT PROMO CODES & LIVE DEALS DO NOT WASTE TIME LOOKING FOR A CODE WHEN THE PROMOTION IS ALREADY A NO-CODE DEAL. PROMIZI | 2026 SHOPPER GUIDE 16
