I asked each of them separately for replacement parts for molds I'd bought from them. The only question was "What's your address?".
True that Miha was sending me a mold anyway, but he gave me all four complete sets of six cavity mold hardware that I asked for, no charge. Tom sent both sets of sprue bolts that I asked for for free, postage also on his dime.
These guys will always get my recommendation, and will always be the first I'll check with when I need to scratch the new mold itch.
