Hey Grok-
I've offered to do that for others, so I can do it for you too.

If you want me to grab that item (I'd recommend the Buy It Now for $45 USD), that'd be $51 USD, then the shipping to the UK. Let me know.

Looks like it MIGHT fit in one of the "Flat Rate" shipping boxes.

Do you know if it will fit in this size?

USPS-Priority Mail® International Small Flat Rate Box:
8-5/8" x 5-3/8" x 1-5/8".
Maximum weight 4 pounds.
$13.95 USD

Next size up is Medium Flat Rate Box - $45.50 USD
13-5/8" x 11-7/8" x 3-3/8" or 11" x 8-1/2" x 5-1/2".
Maximum weight 20 pounds.

So it would be roughly - 130 GBP - 200 GBP
