Used stamps exchanges.

how can you write no definitives in your profile and then send 50% of them?

I don't remember how many definitives I send you. Few of them, that's right but not 50%. I send you many stamps for your thematics. And you write in your profile "definitives OK, but not too many" and in my profile I write "No definitive or common or damaged stamps please." but half of the time I nevertheless receive some of them.
