Not many antique shops in south Texas have a lot of bottles but I found one in a nearby town that has quite a few. They bought a collection at an estate sale about a year ago and have about 500 bottles in their shop. I have bought a few sodas from them and they charged $5. - $15. per bottle. A few weeks ago the guy called me and said he wants to get rid of all the bottles and he just wants to get back the $500. he paid for them. I told him I'd call when I was in town, but I knew right away I wasn't going to buy all those junk bottles. There were only about 10 left that I really wanted and he had not wanted to price those before. And there were some that I would take if they were cheap enough.
I went last week and told him I would make an offer on some of them. I bought the 9 I wanted for $50. and 90 more for a dollar each. I'll start with the embossed bottles I liked.

I haven't been able to find a 1943 7up bottle, yet, but I did find this one from Salt Lake City, Utah made in 1944. Notice it has seven bubbles with an embossed neck and a 4. with a dot on the base....
