Stupid WC Cap Questions

[loramin]

So I just used my WC cap for the first time the other night (it saved me from a Corrupted Seafury), and now I need to recharge it. Having never done that before, I assume I should:

A) Get a charged cap on an alt
B) Camp both chars next to an un-used vendor
C) Sell the uncharged cap to vendor
D) Sell the charged cap to vendor
E) Buy both back

Is that correct, or is there any better way?

Also, does anyone have any recommendations on good out-of-the-way vendors I can use (preferably non-greedy ones)?

One last thing: I tried to trade my un-charged cap to someone with a charged one, and the game told me it was an invalid trade. That seems kinda sad to me: if it worked n00bs could make money running cap recharging businesses. But that's not a bug, it's just a part of classic EverQuest, right?
