What customers say about our store
Quick and reliable service provided! - Scheduled an appointment with Wayne the other day for a Dry Ice order pick up, he will go over and above for his customers to make sure we are well taken care of. Even with a broken foot !
Thanks again Wayne!
You've got my business!
Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
