I just chatted with them:
MarkS: Hi, I just ordered the inland briefcase that your site lists as free after rebate. When filling out the rebate form I see that it says it's only for tigertdirect.com retail outlets, but it's listed on your site as free after rebate???
Myra Sito: Please try to use the tigerdirect.com retail outlet.
MarkS: well, i ordered it online already because your site said free after rebate!
Myra Sito: I understand, but in case the rebate was denied. We have the rebate assurance policy.
MarkS: what does that mean?
Myra Sito: If in case the rebate was denied by the manufacturer, we will be assisting in getting the rebate amount.
