1. Don’t drag your purchases around with you.
I didn’t know for years that there is actually a cloak room area in the main hall where you can leave your purchases and collect them when you are leaving, all for a small fee. For years I was the plank walking around, wide as I am high with shopping, sweating buckets with bag handles cutting the circulation off from my fingers while other shoppers bashed into me. The other upside to the cloak room is that once free from your earlier purchases, you forget how much you already bought and can go do it all again. Your welcome!
