If you’re like me, you check your email multiple times per day. In a perfect world, we’d only get messages that we want. But a lot of our mailbox is now filled with junk mail and marketing messages. I’m pretty selective about who I share my email address with. So I’m usually interested when one of these stores sends me an email. But I’ve noticed a recent trend. One of my favorite clothing stores will email me to tell me that something I looked at previously is now on sale. But when I click on it to buy, they don’t have it in my size. They know my size, so you would think they’d get it right…
