I really don't like bricklink. It's not just that the interface antiquated and clumsy, but also because I think fewer than half of my purchases there have been 100% successful.
I understand that mistakes can be made while counting out hundreds and hundreds of small pieces but, seriously, I feel like any order of more than 50 pieces is just destined to be screwed up. I have bought from bricklink fewer than 8 times since I signed up in 2009 but when I order now, I actually order more of each item than I really want, just to make sure that I get the quantity I actually need.
Anyway, I'm just curious about how others deal with this. If you order 10 items that are only 3-cents/item and you only get 8 of them, do you make the seller swallow the additional postage so they can send you the other two? What if it's 50-cents worth of missing parts rather than 6-cents? Any difference? A dollar? Is there a line somewhere?
I feel like it would be wrong to try and force a seller cover postage for 6-cents worth of lego pieces, so I've never done that but, frankly, I feel like I should get the items I actually ordered and paid for, whether it's 6 cents, 51 cents or a dollar.
Argh! Frustrated am I.
