When I send a lot I always ask myself the question: would I be happy if I receive this lot? If the answer is an honest Yes, than it's okay. I would never, ever send such a lot, even as a new member I didn't. You have probably a lot of these yourself, at least you should realize the receiver has got most of them too.
The sender may have fulfilled all the rules but in my opinion the club is more than sending 100 stamps that are all different, in good condition...I think everybody should try to send nice stamps of which the chances are bigger that quite a few are useful.
I have a whole box of German stamps, it would be easy to send 100 different ones, scoring 5 stars because I fulfilled all the rules, but I think the thought behind the club is more than that. Doing your very best for the receiver! Gerard
