Need a way to take card payments without relying on an unreliable app on your phone? This physical card reader from Square is a great choice for making your business seem more professional. It can print receipts, take card payments including from contactless devices, and it can be used cordlessly thanks to the built-in battery designed to last all day.

Expand and add some height to your pitch space with these grid panel displays. They come with accessories like wire baskets to help you store stock, and you can display your items in numerous different ways creatively.

If you want to add a unique and personal touch to the products you're selling at a stall, there's no easier way than with a portable laser engraver. This is a great price for such a powerful machine, but its compact size also makes it great for taking to events. For an even better (but more expensive) choice, I highly recommend the xTool F1 Lite, which is currently 25% off at Amazon as part of the Spring Sale.
