I was looking at a 12 string acoustic and the site estimates the shipping at 75 bucks. I'm in PA. I ended up buying a Mitchell from Musicians Friend. 229 shipped on sale.

Their shipping cost for a single guitar used to be about 35 bucks and I believe they would ship up to two more without increasing the shipping if you wanted to really stock up. It's gone up because UPS has jacked their prices way up in the last year due to increased demand and assorted issues that we all are aware of.
Hopefully sometime in the foreseeable future prices will start to come back down and/or Thomman will find a better shipping partner than UPS. It looks like right now the only option they offer you is UPS express 2 day, which is part of why the cost is so high. I'm not sure what's going on there because I know that in the past the shipping from them definitely took longer than that in addition to being cheaper.
