Purchased 4 $40 vouchers from dealfind.com for canvases at canvasaurus.com. The vouchers have no expiry date, so a year later I tried to use the vouchers, but the company seems to have vanished. Contacted dealfind.com to let them know & to request a refund, but they will only give me a $5 credit on a future $15+ purchase with them. They said I should have contacted them sooner. The point is, the vouchers had no expiry, and dealfind's FAQ's says that if a company goes out of business before vouchers are used, as long as the voucher isn't expired, they offer refund.
