Don't like the 90 eur minimum
Come on brother, seriously? You're lucky it's THAT low. A lot of the better sources (especially the long time and/or established ones) have minimums 2 to 3 times that.
As established as this source is from a length of time in business, and from an established clientele point, that minimum is MORE than fair.
Besides, what are you ordering from him where that minimum would be a challenge for you to meet? You ordering an item here and an item there?
