If you are a member of Sam's Club or Costco, you do not have to buy in store unless you want to. I do both though.

We have a Sam's Club here and I by instore and online. The nearest Costco is an hour and a half away. I have a membership and only go to the store for my glasses. I have bought a number of big-ticket items at better prices than anyone else. Earlier this year I bought a 36" GE Profile Induction cooktop. The regular price was $2,500.00 Home Depot and Lowes had it on sale for $2,200.00. Costco had the exact same model for $1,700.00 and free shipping. I am now a huge fan of Induction cooktops.
