or, How to Be a Constant Underbidder!
I buy most of my Ebay items from the UK and US, so most items end in the wee small hours when beauty sleep is trying it's best to work it's magic.
I use Gavel Snipe to place my bids for me, and I've had a spectacularly unsuccessful week, with prices heading upwards for the Silver Jubilee material I'm constantly seeking.
Here's a few examples:
First, a cheap stamp. Straits Settlements Silver Jubilee 8c, SG257, with a clear strike of Changi, Proud D2, although no year is shown. I collect the postmarks of the small post offices of the Straits Settlements, and I have no Changi in the collection
The stamp has a CV of £3.25, and Proud rates the postmark as 40, or £4. The stamp sold at double CV, £6.50!
