Strange problem (part rant, part humor)

Hello everyone!

My husband has gotten out his crochet hook again (hooray!). Since I knit
occassionally, he's raided my stash for yarn. He found my Red Heart
black fleck and natural fleck, and started to crochet a scarf. He ran
out of black fleck, and that's when I had to do a search for the yarn,
only to find they aren't making it any more. He's decided to continue
his scarf with plain black.

Why did I have to search for it? Because my husband refuses to shop. He
hates going to the store for anything. If he could have me buy his suits
and shoes without him there, he would. I am comfortable with this stash
raid on my yarn, but I don't have a large stash, and what I do have is
roughly 10 years old or much more. How do I convince him that he needs
to tell me specifically what he wants me to buy for him, or that he
needs to go ahead and order it online, or come with me to a yarn store?

I can be mean and deliberately pick out horrible colors- he's blue-green
colorblind and wouldn't notice. But if he would like to use more than
just the horrible cheap acrylic that is Red Heart, he really should
fondle the goods first. A huge part of knitting for me is the tactile
feel of the yarn in my fingers. This experience is enhanced by really
nice feeling yarn. I'm not sure how I can convince him to expand his
horizons. Sure, I can use the excuse to go out and expand my stash with
really cool yarn, but we are on a budget, and there's no guarantee he'd
want to touch the cool stuff anyway.

Any ideas?

I don't crochet, if that matters. It's one of the few things I don't do!
lol.
