Brick.ie The Irish Association for Adult Fans of LEGO®

Hi, Is there an easier way to get bricks off Bricklink. I really feel I am doing something wrong.

The situation is typically I compile a list of brick with quantities I start off looking for what I think maybe the rare or hard to find bricks Dark Blue Brick, Arch 1 x 8 x 2 part number 3308 for example. I then select the cheapest seller and go through my list typically anyone seller does not have my complete list. So I have to go to the next expensive seller and again go through my list one by one seeing if they have all my required bricks. If the list of required parts amounts to a 1000 different brick types this whole process can take ages and mistakes are always possible. Please don't laugh if I am doing something obviously wrong.

Thanks Jim
