Duplicate content in the title

[ofuente]

Good morning,

I am developing an application that searches offers in the press. The problem I have is the follow one:
When I find an offer that I have already post, I cant use the same URL because it generates duplicate content , as the URL is generated from the title. If I find two offers in different stores (for example Thomson TV) I am studying two options.

The first would be to add a number at the end of the URL
http://www.offertazo.com/televisor-thomson
http://www.offertazo.com/televisor-thomson1
http://www.offertazo.com/televisor-thomson2

Another option I propose would be to add semantic data to provide value (such as the date). For example:
http://www.offertazo.com/01-12-12/televisor-thomson

I appreciate your help.

I would go with the date option and have it stand out but I think you need to think this through to avoid duplicate and low content pages. Many offer sites keep all the offers for a store or a product on a single page. That strategy avoids duplicate pages.
