Home Depot is confusing for me on line, as is Lowe's. I would only add that HD has three identification numbers for a product: Store SKU no., internet part number, and catalog part number. All three are different. I did easily find the two items above on the internet. Printing out the item might be a good idea.
And not only that. Sometimes they have the identical product on line at a different price that their own stores refuse to match! Case in point, the compressor I bought. $100 in stores, plenty on the shelves. Online it was $70 (on sale) but it was sold out on Day 1 so I printed it out and took it to three stores. No go! They will not match. Luckily the next day they had more in stock online so I placed the order with free shipping. The box weighed 30 lbs. and they paid for the shipping!!!!!!! So, not only did they lose $30 by me ordering online but they had to pay for postage from Nevada to the east coast using 3 day Select! Wouldn't they have made more money off of me if they sell it to me for $70 at the store and they don't have to pay postage for a 30 lbs. box??????
Yeah, go figure! I think I'll follow Flash's advice, print it out and see if I can track one down. Picked up some paint at Caboose Hobbies, so I'm armed and dangerous!
