Link an off-eBay auction tracker with eBay's Items I'm Watching list.
eBay provides the Items I'm Watching list (in My eBay → Bidding/Watching) to help you
keep track of auctions on which you haven't yet bid. A corresponding API
GetWatchList, allows you to access the contents
of that list.
But the Items I'm Watching list is rather limited and can be replaced with a custom tracking list [Hack #29] . Although the hack works, there are two simple ways to use the eBay API to make the script more robust and efficient:
Retrieve the title and end date with the
GetItem API call instead of using the
flakier method of extracting them from the auction page
Supplement the tracking list with any auctions in the Items I'm Watching list.
The following is a revised auction-tracking script with both of these improvements.
This script requires all the Perl modules specified in "Keep
Track of Auctions Outside of eBay" [Hack
#29] , as well as
Time::Local, by Tom Christiansen, Graham
Barr, and Dave Rolsky
(search.cpan.org/perldoc?Time::Local), which is
used to convert dates retrieved from the API from GMT to local
