What our customers are saying
The overall experience was great. The only problem I had was when I tried to find the option of where I would like to pick up my order, it would not allow me to do so at the Surprise location. Dan, from the Surprise location kept in contact with me that same day I put the order in and was able to take my order to the Surprise location as he had been to the warehouse and said he could take it with him, In the end, it all worked out. Thank you Dan for helping me out, very much appreciated!
