Guild Wars 2

…. currently all have to be picked up by one character.

This would be fine, but we can;t email goods to our other characters.

This would be fine, but the bank account is very small.

What is the current recommended way for me to place orders on BLTC from several characters, and then to be able to pick those goods up with the character which ordered the goods

There is no way to pick up only certain items from the BLTC. It’s all or nothing, depending on inventory space.

You can expand your bank space, or create a Guild vault. Another option is to buy or craft larger inventory bags, or expand the amount of bags a character can possess.
