So I went to the local HD with the intention to spend $103 on the trimmer. I looked over the display item carefully and then I asked the "associate" for a boxed item. The "associate" informed me through a cloud of what smelled suspiciously like partially digested alcohol that they do not have any. And that they do not do rain checks. And they will not sell the display items.
He offered me a Colt for $140 which, although a good price, is not quite the same as $103. Or rather he would have offered me the Colt at that price - if they had any!
Yes, I can buy the 2401 on line - an pay the postage (apparently I cannot have one delivered to the store). However, this is a "would like" item rather than a "must have" item and by now I am reluctant to give HD my money.
I think I shall return to my previous policy of avoiding buying tools in HD. The previous experiences were kind of consistent with this one.
