Hi,
The various shipping providers constantly change the parameters of their tracking URLs. For example right now the one that is hardcoded for Bulgarian Post:
http://www.bgpost.bg/IPSWebTracking/IPSWeb_item_events.asp?itemid=RI310758456BG&Submit=Submit
no longer works and it simply redirects to bgpost.bg.
I suggest Tindie allows me to specify my own tracking URL, so I can use an universal tracking site like this one:
Thanks!
