I had to share mine, in it's own thread, I am so thrilled!
"Mrs M," a gal I had been in touch with, for almost 2 years, via email (she had bought some plants from me, lives in WA, S of me). Over a year ago, she had mentioned she had some glass panels, perfect for a greenhouse, offering to sell them to me. I told her I would have to save my money. That was over a year ago...
Recently, I was researching Tall Hoop Houses, thinking it would be more affordable, and had figured out where I would buy the materials from. Then, I received (2) books on Greenhouses, both completely different, and highly complementing each other! After skimming one, reading more of the other, I found myself increasingly disappointed to go the Hoop House route. So much so, that I began checking CL multiple times/day, just hoping there would be a real deal on there for materials...
Now, enter today. I thought of Mrs. M, who had been holding the glass panels, so I called her. We began just discussing gardening, what we were each doing. She was VERY frustrated, trying to figure out how to solve her gardening challenges. Just this past week, she had a local gal come out to her place and recommend she do "Lasagna Gardening." So, Mrs. M bought the book, but was very skeptical of that working in our climate (It DOESN'T). It is too wet/cool here for it to work, and helloooooooooo SLUGS

I told her what to do with her property challenges, make her work far easier, and told her how to quickly put together a garden area in time for planting in just a couple days (using everything she already had). She just needed some guidance, really. Once that topic was covered, I brought up the glass, told her I was saving money, didn't know how much she wanted, and she interrupted me. At this point, she asked me if I would allow her to come here, spend the day with me, pick my brain, see what I am doing, and in return she would GIVE me all that glass...
(70) Tempered Glass Panels 3' X 6'. Of course, I instantly agreed, most happily
Shortly after that conversation, I sat down with DH and we discussed my future Greenhouse design...
Soapbox Roof, 36'+ long, and up to 18' wide. Since I just got my Nursery License, this will be a real blessing!
Mrs. M is coming on Wednesday and by this weekend, we will go pick up the panels. Soon after that, we will get the area leveled, and DH will begin building (!!!). I may have it done by next month
A less momentous, but cool Barter?
I am trading (60) Chocolate Mint plants for credit with a Farmer, who is on a 40 acre Certified Organic Farm, running a large CSA, also raises meat Chickens, Cattle, and is a hub for selling WA Grown Organic Fruits and also Raw Milk (from WA Certified Raw Milk Dairies). This past week, I went to meet her, brought her a Spearmint and a Chocolate Mint plant for samples. She has a contract with a Chocolatier for next year. The Chocolate Mint plants will be grown for that purpose. Cool, eh?
