Yes that's a good idea. And also love window shopping as it takes my mind off of everyday things. Would be nice to know that when I finally can go back and buy the item that it is still there to buy
I use BidStart (owned by Stanley Gibbons) for a lot of my auction 'sightseeing'... they have a "Items I'm Watching" option where I can select to keep a Store Item recorded for future referral. I see some nice stamps and then go to my inventory list to see if I have that item... I simply delete the pin if I am no longer interested.
