I purchased 2 - 5010's on Oct 10, and 2 - 7100's on Dec 05. Saw the Home Depot sale this weekend. Brought the still unopened boxes in my car in case I needed to do a return/repurchase. Went to the return desk with my receipts, explained I purchased 4 tools in the past 2 1/2 months, and before I could even request the refund or explain I could bring them in for a return/repurchase, the cashier said "let me make the 20% adjustment". I saved a lot, but this store makes out even better, as this type of attitude is what keeps me coming back!
