I haven't heard much negative about Conn's.
Ashley on the other hand (in Reno anyway...)... yikes. Trying to get the store to honor a website price is a very interesting experience, I guess the markdown comes out of the salesperson's commission or something. Then when they hand you off to whoever takes one for the team and writes up the order with a price match watch what they actually charge your credit card because it may not be what you just agreed to...
Best to go into these places with a t-shirt (preferably a beat up one), shorts, and unkempt hair. It is amazing how they just leave me alone. Talk about a great thing to buy online...
Independent shops that haggle on price can be fun. Some of them will also deliver same day.
