Outpost.com was also the shizznit back in the day. Free overnight shipping + competitive prices was soooooo good. I could order someting at 8:00 PM, and it would be here at around 11:00AM the next day. The bouncy ball they sent me once with an order was sweet too.
buy.com is pretty good. Back in the day of the Palm III, the were selling Palm Pilots for below cost. You could get any Palm for $100+ off retail prices. I remember buying my IIIx from them. The buy one get one free SMC switch deal was also quite sweet.
ah, the memories.
