Having a short time friend while shopping

Last Friday as, I was about to buy my new wallet. At the store of girbaud while I'm looking for a wallet that suits me, there was this lady who will also buy a wallet for his boyfriend. Out of nowhere, she asked me what wallet would I buy. She grabbed two designs of it and asked me what will be the best one for me. I told her that those wallets were both in good quality but I'd rather chose the wallet that fits my needs. While deliberating on what she should buy, we asked the salesman what is the difference of those two. We kept on talking on those design and the salesman told us that if we will get those wallet with the same price, we will be having a discount of about 20%. We look at each other and she said, "go kuya, pili kunin mo yan kukunin ko to" (go brother, get that one and i will get this one). We both agree to it and bought those wallet. The good thing about that is, we have both given a discount and paid less amount than the original price. So if you are going to buy, try to make friends with others and maybe, if that stores offers a discount for buy on get one, you can have that item less than the original amount and also have a new friend.
