i have said it a time or two in the past.
i fill out any form, take photo copies of everything
then i mail the original forms and proof of purchase, via Certified mail, with a return receipt of proof of delivery.
i have done so as long as the rebates are at the very least $25.00 and up.
any rebate lower than the $25 they offer, i generally just make copies, then mail it.
nearly all rebates say something like, "allow 4 to 8 weeks for your rebate"
after the 10th week..??
i get busy and start calling, and emailing.
i allow at least that extra 2 weeks for the mail to get here...
and the more people applying for rebates, prolongs the processing times.
