hey @crossovertees , your site is well-designed. Would recommend not to bombard an email sign-up when visitors first land on the page.
I also like you are tailoring by special occasions like the May 4th.
Have you try posting your t-shirts on Pinterest? There are people finding T-shirts there these days. And yes, the a-b testing proposed by @PageFly-Kate is something you have to experiment on. Tiny changes make a big difference, and it takes time to fine tune.
As to discounts,
You can try our plugin to allow your users to play a discount code spin wheel game when they first visit your site. They have to enter their email to play. It’s a win-win situation!
You should give our free product a test drive
Good luck with your store!
