What a shambles this company is, nothing is straightforward. Apparently, you pay, claim the voucher on the app and have the items sent. I don't know how long it expires, once it does no refunds are issued, they give a credit note instead. They keep insisting you repurchase it again even though you don't want it. This simple request goes ignored. Refunds are not negotiable. This is a con and a scam. They've scammed me and are they scamming the store by holding their funds by not placing customers' orders? Regardless will warn people to avoid this unethical, thieving site.
