I bought my T2i from them online. Best deal I could find. Plus I paid for it over 18 months interest free. I very rarely go to the brick & mortar store for anything. It's either buy online or go to Fry's if I need it quick.
My son bought and returned three 46" TVs from them. Two Samsungs and a Sony. They all had problems and Best Buy took them back with no hassle. On the fourth try he got a Sony that worked properly but there was a $200 difference between the online price and the in store price when he went to the store to pick it up after ordering it online. Seems the online department forgot to raise the price back up after the sale. The store manager got involved and although he had to pay the higher price in the store he contacted their online customer support the next business day and because the store manager had thoroughly documented the incident his Best Buy credit card was immediately credited for the $200. Plus he got to pay for it interest free over 36 months.
No big store is perfect and in my opinion Best Buy is no better or worse than any of the others.
Also I don't take any pleasure in seeing any store close. Real people like us loose their jobs when that happens. If you don't like a particular store don't shop there. But don't root for it to close.
