I just looked at your store, and I must say I loved the products! They look cool as hell, and I don't think the price is the problem either. I do have a few suggestions tho.
1. Include product benefits on the front page. You have the product name, image, short description, CTA, everything already. But you don't have its benefits listed. People need to know what they could gain from buying them. Keep this short and concise, don't write more than 90 characters for each of the benefits. Maybe write like 3 benefits or so.
2. There's a long way between traffic and sales, and there could be many problems in between. But the main problem is probably shipping time & fee. If the order takes too long to deliver or the shipping fee is too high, people might abandon their cart. Also, with a product like this, in-hand examination is probably better than delivery
=> use Store Pickup (basically allows customers to pick up their items in store instead of delivery). You could do this by using an app on Shopify App Store or use the included SHopify option (it sucks tho). If you are not sure, read this checklist to know for sure if you need it.
Welcome to Shopify!
First off, I love your story - I can see it is something you’re really passionate about. And it’s a great cause :)
I believe it is this very story and passion which is probably shining through in the face to face sales, and isn’t coming through the website. Here are my observations:
I hope this advice helps out. Hoping for more sales in your store!
Just a quick observation: in the three first seconds I visit a site, I want to know what it is, and also persuaded to want to know more. Your website does not provide that for me. Granted, I may not be your perfect customer since I do not look for that type of product. At any rate, I looked at your Instagram and there, for contrast, I was able to learn what your business is all about, hand blown glass/terrariums/tealight holders. My slight suggestion would be that you find a way to communicate your business/product in a fraction of a second through strong visuals and copy (such as the one you have as a descriptor on your IG account).
