Affiliate Marketing Secrets

He bought the Nexus 7 at Walmart and, after he bought it the price went down. He bought a Sony Bravia TV from Walmart two years ago and, after he bought the TV the price went down so he took the receipt to Walmart and, they gave him the difference we had the TV almost a month before taking the receipt to Walmart. I called them today about a reimbursement they said that after seven days after purchasing the item that they can not reimburse the money because, it has been twenty four days. My boyfriend called Google and, some other places that the Nexus 7 is affiliated to one person said if he had bought it from the play store that the play store would have reimbursed him.
