A treasure hunt is a creative way to engage your customers and make them want to be in your store or e-commerce website. They will get to browse your products and offers while hunting for discounts. If your customers find discounts, they will most likely purchase something from your store, because they earned the discount and they will not want to lose it (loss aversion effect).
It is a fun and original idea so you may get some free press thanks to organizing such a campaign.
You can create various campaigns (gift cards, unique or standalone discount coupons) and place the gift card and voucher codes on the website or print out the QR codes. All the limits on coupon validity and a number of times they can be used can be done in the Voucherify dashboard so you do not need to worry about crossing the promotion limits. You can track the coupon redemptions from the dashboard and remove inactive coupons from your website manually. Do not worry, if someone uses a coupon that has been used already and cannot be redeemed any more, they will see an error message and they will not be able to do so.
