Every month I make a trip to visit my Mom. It's about 100 miles away from my house so I always have to plan pretty carefully. Along with visiting her, I scope out things I can put on eBay.
The town where she lives has some pretty interesting shops with unusual items. A little shopping around can pay off later. In fact, since it's getting colder weather now, I'm going to be looking at electric blankets. If I can find them at a low enough price, I'll get one for myself to cut back on heating expenses, and I'll get a couple more to list on eBay.
Because I write reviews, shop for items to sell, and conduct other business while I'm visiting, I can usually write these trips off on my taxes. In fact, rarely do I go anywhere that doesn't have business as the goal.
Last year, I took a trip to Branson for a week. That was entirely unrelated to business and purely for pleasure, so it could not be written off. But these shorter trips, a few times a month, are when I really am looking for items to sell or topics to write about. It's when I take some pictures, too, so you can see what I've been up to.
