Preethi Chef Pro & Sumeet Mixers in NJ

Hi Everyone,
I wanted to know if the there is a list of stores around Central NJ, in edison and also if there are good online stores that you know of, where one can buy these mixers at an affordable price.There are some stores which are just pricey and I feel shoould be totally avoided.Additionally what is the price range of these mixers.Was seeing the current price of Preethi Chef Pro Plus, it was showing up as $175 on Distributors for preethi mixie, sharp wet grinder, nirlep cookware, Cutting Edge microwave idli cookers, Akshaya electric idli Steamers and Cookware, dry, wet grinders, mixer grinder, indian mixie, 110 volts, tabletop, countertop, tilting models

Do these two brands ever go on SALE.Is there any particular season good to buy these mixers, like closer to Diwali etc.

Do let me know.
