Reusable bags are a great thing. Please continue to use them when you shop. But be aware of the procedures for using them at the self-checkout.
Many stores need a clerk to verify your coupons, at times entering them in, so head to the main checkout path if you have a lot of deals.
When browsing all the apples and tomatoes, it's easy to second-guess yourself, particularly if you bought something unusual since it was on sale.
If there’s a long line at the self-checkout, some people feel anxious and rush through it. This can cause mistakes which need an attendant’s help.
Personal weight is crucial during self-checkout. Weight is usually used by most machines to verify purchases.
With more things, it takes longer, you're more prone to make errors, and the queue behind you is longer.
Team up to speed up checkout with a partner or friend. Having one person unload the cart while the other scans and bags works great.
