I do see it as a TeeSpring problem. This particular bug got in my way 2 weeks ago when I was attempting to buy some merch to support a youtube channel I frequent. I almost abandoned the purchase.
A shopping site breaking checkout when there's a google analytics problem is madness, IMO. uBlock Origin is hugely popular. With 10M (claimed) active users, you should probably be testing against uBlock Origin for your e-commerce site.
As an aside, buying from TeeSpring was a little... interesting. You add the items to your cart and pay like at any other site. Instead of being charged for the total, I got invoiced separately for each (including separate confirmation emails), along with 5 or 6 duplicate shipping notices for one of the items. My credit card was also charged separately for each item. I get that there are probably reasons for this purchase flow, but it's not implemented well.
I got my stuff and all is good, but the whole buying experience was janky.
