As a contest lover I know the frustration of getting to the grocery store and forgetting some of the contest promotions that are running. Leaving the store getting home and then remembering that I forgot to grab a specific product for a contest entry.
I have won so many amazing prizes, like an Oculus, grocery gift cards, NFL gift cards, gas cards and more. It's totally worth entering purchase needed contests even for someone new to contests.
Please note: Not all receipt promotions are contests. There are often receipt promotions that offer you a freebie for uploading a receipt of a particular product. Much like the Reese candy bowl promotion, or the Orville Redenbacher promotion. When those types of promotions are running they will be in this list below too.
There are such great odds of winning spectacular prizes with receipt promotions, UPC contests and pin code contests.
Always remember that when it comes to purchase needed contests there is always a no purchase needed option.
