Personally, when I get bonus seeds, they are for the most part something I would never use, and end up re trading, or freecycling since I would not want to hurt someone's feelings to re trade something they sent me. I am not a seed hoarder, so just like to have seeds around that I intend to plant this year. So, having seeds I don't need tends to mess with my head. It messes up the order of things. I tend to offer them up as SASE, so I have order in my little messed up world again.
Some, feel they have to send bonus seeds for some odd reason.
Others probably get all upset if they do not get bonus seeds in return.
I actually did not even know about bonus seeds on my first trade but did send some unasked for eastern red bud seeds, since they are plentiful in our yard. She thanked me, and said she can't grow them in her area, but would give them to relatives or something. I then felt sort of silly, not asking before I sent those. I don't send seeds out of the blue anymore. Seems like a big chance they can't use them. I would rather send seeds to someone that truly wants them.
I live in the south and most stuff won't work here, from northern veggie varieties, to European flowers. I only plant natives of Texas and the southwest (for non edibles), so it is a big chance with me that bonuses are not going to work here.
They are a nice gesture. I just don't say anything about the bonuses I can't use. I don't want them to feel like I did after I sent un needed seeds. I know, I know, I am sensitive. I just don't want anyone getting upset with me for not sending a bonus pack. I try to be very generous if I have plenty, and be very honest with exact seed number, when I don't have plenty.
I guess what I am saying is, if you want to send a bonus go ahead, but never expect one in return. They are really never part of the deal. I think if you are trading for 2 things and each send the 2 things and 1 bonus wouldn't it be nice to be able to pick that third thing, then you both would get 3 useful things and not 2 good things and a item you have to re trade.
I guess some like fun surprises. I don't know, I guess I am up in the air about how I should feel about bonus seeds. I guess I would really enjoy a bonus of seeds I could use. like Lima beans.
Like I said, I go back and forth on this issue. And I do not want to hurt any one's feelings with this post. I did inherit hoof in mouth disease from my father, so I have probably said something to bother someone, so sorry in advance.
Ok, I have sent unasked for seeds now that I think of it. So that makes me a nut! But I don't expect them in return.
