I have applied 5% discount across all my prices here on BrickOwl compared to Bricklink (it shows as sale - but it isn't) - as I cannot have different prices whilst keeping "sync" with BrickLink.
'Tis the only way I can pass on my savings to the customer!
I don't think I can advertise that on BrickLink! But if you do find my alter ego you will see that it is so
my username is the same
