The OCZ SSD Rebate is for $10.00. The product page incorrectly marks it as a $20.00 Rebate under the "Rebate Information" Section.
Also, Both rebates do require an Original UPC, however, they are advertised together, so it likely won't be an issue.
I advise doing the following:
1) Mail a copy of the UPC for the TigerDirect Rebate, Offer #TD-20685.
2) Mail the Original UPC for the OCZ Rebate, Offer #OCZ-12512.
