the tesco analogy is correct in very similar ways to be honest, you say you dont haggle or get a discount at supermarkets…BUTTTTT have you all forgotton most stuff in tescos etc is heavily discounted? one cheaper than the other chain, and then one cheaper than that chain etc etc etc….beer especially, 2 for £14 for 2 crates??? how much discount is that off the rrp??!?!?!?!? so it is comparable to some extent! you dont feel the need to haggle as its already discounted at tescos! you look on the receipt at the end of the shop, and its usually around a tenner off or more from £100 shop….that to me makes 10% discount! like it or not discounts and bargains etc drive punters to buy!
im personally in the if its your local shop, get to know them and use them abit before trying the abrasive give us a discount card! it took me a while, but chatting and having a few jobs done there has now got me a discount on most things i buy there!
