I almost want to cry ;( writing this review because I dont want people to find out about them and rather keep them in my pocket but they deserve it…
This company is great with Quality Products at amazing prices! Sometimes, their website is not the most accurate but is user friendly and if you got questions they will call back and are very prompt in responding via a call or text to verify inventory before placing an order.
I really appreciate and look forward to continuing to work with you all especially Anthony — he is amazing & the best!!!
