Question on Price Match Guarantee

Moderators, if this is in the wrong location for this topic please relocate.

I was recently on this website ordering supplies for my pets. Petstore.com I noticed they have a neat mod on their website, the price match guarantee. Its located by the “add to cart” on each product page. You click on it and it opens up a jscript and you put in the url of the website that has the product cheaper, the price that website has the product as, and the shipping fee they are charging you. Then it simply adjust the price in the cart to the competing website price. It is then explained if it is found not to be cheaper with tax, shipping, etc that the price will be readjusted.

Does zen-cart have a mod like this or the ability to handle a mod like this?

that is an oscommerce mod. don't bother. it's a pita and 99% of those do not fill it out correctly and most are tire kickers wasting time. but if you must have a similar mod there is one in the mod section. do a search for 'cheaper'
