Dear compared to what? A bedroom trader that's likely not send your bits out and you have NO remittance if the parts are fooked, not as described or simply NEVER sent?
Or should traders do it for free? No mark-up, just sell it all cheap to keep you happy?
Everyone's gotta make a living and I know it probably wouldn't make a great deal of difference financially, but I'll bet if McDonalds stopped paying you a salary for flipping those tasty burgers you'd have something to say about it.
