I just can’t recommend Shoptimizer enough. I feel like I’m on a first-name basis with some of the crew, they’re just so unbelievably helpful, no matter what the question. Their products are also so beautifully well made and easy to maintain, they’ll last for years to come.
Every order from Shoptimizer has been an amazing experience. their site provides lots of detail so I know exactly what I’m getting and their customer support is just outstanding. I needed to swap an item for a different size and they arranged everything for me within 24 hours.
