Many times - they're good. Actually if you go to http://www.blu-raystats.com they show Amazon and Deep Discount as the 2 primary mail order companies and have side by side pricing if you want to compare.
beats me - maybe because I took the additional $5 off . . .? I tried adding the stocking several times but each time it would not give me free shipping.
If you give them your e-mail (top left of web page) you get $5 off (presumably for first time shoppers). I got blu-ray Planet Earth for $29.99. Beware - do not accept "free Christmas Stocking" - it raises shipping from FREE to $5.75.
the penny deal is because it won't tune to DTV, only analog, therefore Philips is not allowed to sell these sets - without full disclosure. So they're making the money back on the shipping . . .
