Not yet. But I have been impressed that you are keeping prices competitive, and a wide variety of brands/selection!
The only advice I would have, is perhaps try to continue to improve the mobile (phone) experience. Browsing is a bit cluttered at the top of pages, but excellently done when actually scrolling through a group of products.
Also, the little “live chat” or “chat now” buttons are a personal annoyance that I feel would be better moved to the menu, but I realize that some like them.
@Vapesourcing thanks for the opportunity and giveaway!
