Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

It's mostly good, only some item's are easier to find through the search than the menu

The purchasing process is fairly quick and straightforward and for me user friendly so it probably took more or less than 3 minutes to purchase and pay for the items. I wish there was a discount offer for multiple items to encourage us buyers to purchase more an incentive and add more sales in your end. Besides that, it's been a great purchasing experience and will continue to shop as I am a repeat customer and have bought from your store many times before. Thank you.
