I'm going to go out on a limb and guess that someone is not familiar with the current market on the HL Stamp Series. $395.00 for an 80% complete stamp series that originally retailed for $230.00? I can't find the bid button fast enough.

The last two complete sets I saw went for less than $150.00 per set within the last month.

What is the current market for a HL Great Lakes Stamp Set?
The current market is what someone will pay to own a set of these five lighthouses. In this auction, four!

The retail pricing at the 1995 release was $292.00 if purchased individually, or $275.00 as a complete set.

This auction states $395.00 with a BIN price which includes shipping to most of the US. Or the bidder can submit their best offer.
