[quote name='chadthechosen']can you use different emails on this but put in same address info?[/quote]
Yes, if you're willing to fill out the information.
I haven't read the rules of the contest, but you may want to look and see if there is a section on multiple emails from the same address. I mean, if you use the same address every time, they might take note of it and refuse to let you claim winnings.
Filling out the form took me about 1minute including page loading and the prizes per day seem to be barely worth the effort unless you want a lot of coupons.
BTW: The period trick DOES (seem to) work.
