Old Service Merchandise shopping cart spotted in a Salvation Army Thrift Store parking lot.
SM was a rather different store. It had an area where you could just grab stuff off the shelf like any normal store, but its electronics, jewelry, and furniture departments had a ticket system. Basically you got a card and wrote down the catalog numbers of what you wanted (later this became a barcode "pull-ticket" system), then took it to a counter. A few minutes later, your "order" would then roll down a big convener belt to the checkout. This method pushed the catalog and reduced theft. The chain liquidated in 2002, and currently exists as an online retailer.
