Just received this email from the rebate center.
" Good Morning,
I have reviewed the submission and the WalMart.com receipt submitted has no date of purchase on it..This would provide us with proof that the product was purchased within the allotted time frame for this promotion..If you can provide me with the date of purchase I will be able to validate the rebate..If you have any further questions or concerns please feel free to contact me directly..Have a great day.
Thanks,
Theresa B.
