If some of you want to pay full price for what you buy and what you pay for, more power to you. I have never seen any problem with asking if any retailer can offer a better price for anything, all they can do is tell you no. No sense in criticizing folks who ask for and receive discounts just because you don't, or don't want to.
I see no problem with asking as it never hurts but I dislike when people complain that they didn't get a discount. I'm not going to the grocery store and expecting a discount on anything or going to Cabela's and saying I want a discount or I'm telling everyone your store sucks. Just ask and if they say no just go about your day and maybe try another time.
