i always ask Ray if stuff is in stock now before i order anything. it saves him from having to do the time juggle, and it gives me a realistic timeframe for when i will get stuff... i'll usually chat with him and ask if certain items are in stock. i had a post a couple weeks ago about the flex strips. he's really good at telling you how many he has in stock, and when more might come in.
also, for the connectors, he has 2,3,4, and 5 conductor connectors. i might get some other stuff for use with other items. (like using a 4 conductor connector for connecting rgb strings (without an IC) to the mr16.)
