My name is Alexandria and I own My Girlfriend's Wardrobe which is an online + brick and mortar consignment store for women. We carry designer and name brand clothing, shoes, handbags, and accessories. You can check out our website at www.mygirlfriendswardrobe.net. I started using Square because I needed a way to accept credit cards while at events with our mobile store we occasionally break out. I fell in love with the ease of use and have really enjoyed most of their new features. 

Since I have a consignment store, 99% of my items I have just one of. There are a few retail items I carry which I keep saved in the items screen. Everything else I sell I add at the time of the sale. The new + button is great for me since it adds items directly into my current sale. I love their tickets feature because it allows me to get items ready to go home with customers while they continue to shop. I've created categories for my items (tops, designer handbags, etc) which really helps me know my business better. The category feature allows me to print reports by any date range which is great. It allows me to see what my best sellers are during any time period so I can always be prepared.

Currently I use the Square stand, marketing features, card reader, feedback (free version) and their reports via the dashboard. Their reports are some of the best for a free POS app and I've had many places try to steal me away from Square but they can't beat the rates AND give me the same report tools. 

One of the challenges I face are exchanges. I have been recommending this feature for almost 4 years now and while it doesn't happen often for me I wish there was an easier way to do an exchange for an item without having to create a $0 item and add that to the sale of the new item that says exchange of xxx, then edit my day to day sales reports for the item that was exchanged.
