Ahhh...I'm on that adventure right now. Ordering from a manufacturer can be really expensive. Not the cost each. But, you may have to order by the pallet. So far, I have discovered a company called Fairway Glass. They cater to smaller orders. I requested some samples and they were delivered in 2 days. Unfortunately, I cannot use their jars. The quality is outstanding. It's the fitment for my application that keeps me from buying. So, I found another possibility. They are called The Jar Store. They also own Decor Trends. I just called them a few days ago for samples. So, I don't know if they are good or not. Last year, I had problems with the fitments. They promised me, they changed manufacturers. That's a good thing. Besides, samples are free and I will test them to make sure wll before i buy. Another place you could shop is a restaurant supply warehouse. Beer mugs, coffee cups, Irish Coffee Mugs and a bunch of other glasswares. I had beer mugs and Irish Coffee mugs coming out of my ears. They sold quickly. I don't remember how much I paid for them. But, it was a deal I could NOT refuse. They were either Anchor or Libby. I forgot. You can shop at a Dollar Store. But, you are taking a chance. You don't know who made them. You don't know if there is enough silica in the glass to keep it from shattering. Above all, you don't want a certified letter coming from someone's lawyer. I hope this helps. Rick
