I sent in my forms too. Though, I stapled, not taped, the UPC's onto the forms. I know they received them, cuase I sent them registered/return receipt. Got the receipt back...from USPS...so, now, I am waiting for the site to be updated. It would be cool if I got the rebate back, before the 15th. That would mean a 135L or 200L...the race is ON! Otherwise, I shall wait till the spring rebates, and see whether they are 'triple' in nature...or still 'double' for that time period. Who knows.
And yes, they do want it filled out, it said in the rebate form.
