Best Sales Clerk ever!




Stopped in thinking would purchase only 1 item and ended up walking out with 3. Heather was so knowledgeable and was so pleasant to work with. I have been to many appliance stores and she was by far the nicest, sweetest, and most hardworking I ever seen. And very smart. She took her time and never made me feel rushed. I couldn't believe how even though I went in with idea of maybe buying 3 I actually did! Way to go Heather.

service top notch




I called and asked if could have me on a monthly plan of dropping off salt every month to my house. They were happy to do so and giving me a good deal. One less thing I have to worry about doing they were happy to take care of me.
