Auction Napa Valley wants you to bid and bid often from the comfort of your own home. You don’t need a fancy gown or a tux to bid online in their 4-week Net auction which begins this Sunday at 8 a.m.

A worldwide pajama party? Hmmm …

Does this mean if you’re a sleepwalker, you could unwittingly bid away your nest egg?

Okay, here’s the skinny. This year’s online auction has 150 lots of wine – plenty of loot — wine collections, large format bottles and vintner-hosted excursions. To check out the lots, here’s the link: http://bit.ly/LX41t

Last year the online auction was only 10 days but organizers decided to expand it to tap world-wide generosity, as well as market the auction globally. The Napa Valley Vintners — the group organizing the auction – is a trade association, after all, and it always aims to get as much marketing mileage out of cash-raising efforts as possible.

For the curious potential bidders, here’s how the E-Auction works. There will be four separate online auctions and each one will have a theme.

Here’s the roll out:

Week 1, which opens Sunday (May 9 at 8 a.m.) and closes the following Sunday (May 16 at 6 p.m.), features wine collections in bottles and magnums.

Week 2, which opens Sunday (May 16 at 8 a.m.) and closes the following Sunday (May 23 at 6 p.m.), features 3-liter bottles and up.

Week 3, which opens Sunday (May 23 at 8 a.m.) and closed the following Sunday (May 30 at 6 p.m,), features wine and vintner-hosted day time activities.

Week 4, which opens Sunday (May 30 at 8 a.m.), with the finale closing (June 4 at 3 p.m.), features vintner-oriented gatherings, big dinner parties and travel. (This one ends in tandem with the Napa Valley-based Wine Festival.)

In this economic downturn, it’s wise to tap a wide pool of bidders and yes, to include the less well-heeled — those who prefer to bid in slippers.
