Actually funny you mention this.
Saturday I found a decent PRL Corduroy SC. It seemed to be poorly hidden by another thrifter, perhaps in hopes of an upcoming half price day. It was only placed inside another sport coat, leaving the label quite clearly visible. Turns out, Dustinmyself hid it because he was on his bike and decided to stop in, but had no back pack. It was at my house by the time he returned.
Moral of the story: If you like it, buy it now. If you don't....someone else will.
Alternate moral of the story: If you hide something in my territory, you had better hide it well.....or I will find it.
How long does it take for you to "do" a store? There are three on my regular route, all standard-issue, each about the floor space of a supermarket. Because I steal time during the work day, I have to be quick, so it's generally between five and ten minutes per stop, which leaves enough time to check the men's section for new stuff that has shown up since the day before and not much else, with trousers and short-sleeve shirts usually getting a very cursory inspection. A thorough check, not counting the women's section, takes 30-45 minutes. If I did that consistently, I wouldn't have a job or a marriage.
This subject may have come up before, but I'm impressed by how often you score in an area of the country where I wouldn't think that someone could score so well. I'm thinking you must be putting more time into it than the rest of us schlubs.
