Buying from Frys was the best...they took back everything no questions asked. Buy brand new subs...put the old blown ones or some other crappy ones I got from a friend and return those get my money back.
Best buy actually used to be really good on returns also, i remember i took my ps2 in after it broke, i didnt have a 1 or 2 year warranty i didnt even have a reciept and i said i bought it there... Dude went to the register for 5 minutes and was like "sorry we didnt have the same model in stock, all i have is the brand new ps2 with the ethernet access". Lol i was like "welllll... Okaaay"
I also bought a stereo ther in like 1999 with the 2 year warranty, few months i returned it and got the brand new model, then i returned it again but paid an extra 60$ and they let me upgrade to a even better stereo, then i returned that and they didnt have it in stock so they let me pick a stereo that was priced like $30 more for free
And i used to take in other peoples broken stuff too lol... I wish places still did that shit. Last thing i returned was my blu-ray player which i had full warranty on, they sent me to a long ass line and instead of giving me a new one, they sent it to china for 2 weeks to fix it and didnt give me a loaner.
