There’s a M&S Outlet where things are cheap but still fancy enough to pretend you’re a secret millionaire. You’ll find deals on Percy Pigs and jumpers that look like they cost £200. It’s the perfect place to buy a “treat yourself” item that you’ll justify with, “But it was on sale!”
If you’re more into sparkly things, the gift shops have everything from keychains shaped like the Bullring to giant teddy bears that won’t fit in your car. I bought a pen that says “Birmingham” and honestly, it’s the most productive writing tool I own. True story.
