Is there a way i can check a website out of stock from all products everynight?

Is there a way i can check a website inventoryfrom all products everynight?
For example i want to know what the is out of stock every day so i crawl his site and check whats out of stock
is there a way to automate this?

 

You mean you'd want to access another persons database of inventory? Not sure if that's possible/ethical.
Your request is kind of vague, could you explain a little better?

 

yap it can happen in PHP or ASP

 

Define a re-order level for each item so whenever you need the list of items that are going out of stock, you can call a function to get the list of items that are (current qty < re-order Qty).

 

I don’t want to access another persons database
I just want to see if they are out of stock of an item and i want to check my list against threes
Basically i will be selling there products but they cannot or will not bother with giving me inventory lists and it will be to time consuming to do it manually
so i want to check if any item went out of stock or is N/A on there site every night
is there any such system out there or do i got build it myself

 

If you know the exact page(s) with your item list that shows the current quantity it could done using php. If the pages are dynamic (for example: sorted list), then it would be a difficult but possible job.
Can you list down the page(s) so I can give you some more ideas?

 

Yess we have been doing that since a very long time
