Thinking like a Business

Ha, just saw this at the post office. So they have just started adding gift cards, wow, to me this seems like business owner no brainier. Especially due to the fact that only 80% of gift cards are redeemed. To me it is no wonder this business isn't making it. Why would you not offer gift cards from day one, it's like having emmediate cash flow with out products or services being exchanged
