After a few months of being nice I'm a bit reluctant to give free samples.
Now I have a product - a magnetic wall chess set - that want to sell in larger quantities at a low price. So I contacted a few stores from Western Europe and two of them based in Germany asked for samples. I agreed to send them a free set each if they would pay for the transport - which is at most about 30 Euros. Only one agreed. The other gave me this reply:

"Dear Sir,

(...)
If you are interested in a chance
to make business with my company, you to send a free sample
with free delivery."


I'm not sure that I, representing a small shop would be interested in a chance of doing business with a big company with a cheap behavior.
After all, in the past months I've encountered quite a few people with plenty of money who haggle for fun and would never ever consider paying for stuff.

Long story short should I pay the 30 Euros or get myself a few new arrows for my bow and have a great time shooting them instead? What would you do?
