All you have to do is submit the right information back to them and you'll
get the rebate.

Usually to get a rebate it's an original, or copy of, the store receipt, an
original UPC bar code from the item and a filled out rebate form

It's not rocket science but people do manage to flub it up.  My mom just
recently screwed one up - she sent in what she thought was the UPC code but
it was not - so she got all her stuff back from the rebate company and she
simply resubmitted it to them w/the correct UPC.

Can't you just submit the correct info?  What are the conditions that are
difficult to meet?

actually
this speaks very well for science diet

it;s the first time i;ve ever heard of a customer submitting a rebate
incorrectly
and getting it returned in order to have the error corrected

generally, most mfgs just throw out the incorrect rebate thus never even
allowing
a second chance!
