Quoted from Mike_M:
I've contacted a couple of local glass shops to get estimates for standard playfield glass in bulk. So far the best I've gotten is ~$46/sheet. Waiting to hear back from a couple more places and hoping for something a bit lower. I'll post an update once I have all the estimates; if I place the order I'm happy to sell the extras to Pinsiders at cost as long as you're willing to pick it up- I'm in Sterling, VA.
Allentown is coming up in May.. there will be cheap glass there. Also, if FPO ends up happening, Trent usually comes and brings really cheap glass (if he arranges it up front). Unless people are time sensitive.. you'd be better off waiting till those events or cutting a deal with someone like Trent to arrange a bulk buy/pickup.
Literally he brought a PALLET of glass last time and sold out in 2 days. I think he had it as low as $20 that time... but I think the $35 range is more frequent for new glass.
