The SAM4s SPS-530RT cash register is one of the four in the SPS-500 series. The 530R was designed for the retail stores and is a best seller in the c-store, liquor store and small grocery space. It is a workhorse however wear and tear will require you to replace some parts from time to time. We stock the common parts and can order the less frequently needed parts. We also offer repairs and support. If you are a DIY (do it yourself) owner you will find a wide selection of parts available here. Remember to back up your program before attempting repairs and unplug the register from power. If you don't know how to make a back up please check out our how to video we made just for our customers.
