Today I went to a couple stores for a couple adjustments.
Over the phone, store #1 said I could get the adjustment as long as the purchase was within 7 days (apparently only 7 days for adjusting prices of clearance items). When I got to the store they balked, but I explained I had called, etc. I also suggested a return/rebuy but I was told since there were no more left, if they went to ring it up again it would come up as a penny (NOT TRUE, since they punched the SKU in for a price check and it showed the lowered clearance price, not a penny). They then "did me a favor" and return/rebought
Second store I went to get an adjustment at gave me zero issues. No 7 day bs, no "its going to ring up as a penny" bs, etc. They just returned the item, credited me, then re-rang the item.
Third store I was looking for the miter saw.....their price is still 200, but store #2 has it at 100. Store #3 says they dont match clearance pricing from other stores, but that I could buy the saw if they had it and they would give me no problem adjusting it if it went down to 100 (unclear on how many days....30 or full 90). Not sure if they have one, and I dont need it so it would only have been to flip it on CL or something. Not really in the mood for dealing with schlepping a heavy *** saw thru the snow in my truck.
TL;DR - Home Depot stores seem to make this stuff up on the fly sometimes. Other times I truly believe they have come up with their very own policies and since then they have "just always done it that way". Ive heard great things about HD corporate, it would be interesting to give them a call and ask if these policies exist or not.
