Can you tell me more about your Groupon scraper?

I’m trying to collect data for 4 locations (Kansas City, Louisville, Chicago and New York) on a daily basis through the end of the year.

Right now I visit Groupon (almost) every night right before the deals close and mark down the deal information. There’s got to be a better way!

I would greatly appreciate any help or advice.

Thanks,

Nick

Just to let you know as a vendor who worked with groupon in the past, they average 45-50% of the deal as their commission. If they take less than 50% as their fee, Groupon charges an additional 2.5% in credit card processing fees to the vendor. I love you calculations but they are a little low.

Hey Paul,

This is great stuff. I was just wondering where on the website you managed to get the data from?

Thanks!
