I have a few more SmartCarts available. You can buy them here (http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575164389&toolid=10001&campid=5337944278&customid=&icep_item=142101168713&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg).
I have ordered 30 more SmartCarts, and they should be available in about a month.
