Crock pots in a wide variety of sizes are available online from sellers such as Walmart, Amazon, Crock-Pot and JC Penney. While the 10-quart size is not always readily available, sizes from 3.5 quarts to 8.5 quarts can be purchased daily, according to Amazon.
One of the largest models of crock pots, the Maxi-Matic MST-800V Elite Gourmet, costs $53 as of 2015, according to Amazon. Mini slow cookers may be purchased for as little as $20, while larger crock pots may cost as much as $129, as of 2015, according to JC Penney.
Crock pots are available in stainless steel and stoneware, according to WalMart. Cookers are often dishwasher-safe and usable as serving dishes. Most crock pots feature a see-through lid to allow easy visibility. Some crock pots, such as the Crock-Pot Hook Up Connectable Entertaining System, are manufactured to connect together to create a buffet table setting. Colors like metallic blue, sage and copper are available as of 2015. Models like the Hamilton Beach 33473 Programmable Slow Cooker can be programmed to minimize the need to watch or stir while cooking, according to Amazon.
