Devin responded to one of my offers. I didn't see anything on his list I wanted, but, because I realized he was a young person and probably just getting started, I offered to send him seeds anyway if he would pay for the postage. I even offered to provide the bubble envelope for free. Devin said he wasn't willing to send more than one stamp. I explained that that wasn't enough for a bubble envelope, but he seemed unable to accept (and was kind of whiny) that I wouldn't send multiple packs of seeds in a plain envelope. Maybe Devin would act fairly in a swap, but I think he needs to gain a little more maturity before I'd ever trade with him. If you try to set up an exchange with him, you may want to address the envelope situation unless you are OK with a plain envelope.
