How to Use Coupons with GTBuy Spreadsheet
The gtbuy spreadsheet discovery process and coupon stacking create a two-layer savings system. First, use the spreadsheet to identify the lowest base price for your target item across verified sellers. Second, apply the appropriate coupon code at checkout based on your cart composition. Third, for maximum savings, consolidate orders to hit higher discount thresholds.
Our testing shows that combining spreadsheet price comparison with strategic coupon selection produces 28-42% total savings versus marketplace browsing without either tool. The key is patience: rushing to checkout without checking both the spreadsheet and active coupons leaves money on the table every single time.
Stacking Strategy
Not all coupons stack. Our matrix below shows which combinations work together. Generally, percentage discounts stack with free shipping codes, while fixed-amount discounts rarely combine. VIP codes are the exception — they override standard discounts with higher value but require purchase history.
| Primary Code | Stacks With | Best Scenario |
|---|---|---|
| GTBUY10 (10%) | SHIPFREE | Medium order, first purchase |
| BULK25 (25%) | None | Large group buy orders |
| VIP30 (30%) | SHIPFREE | Repeat buyers, high volume |
