Arby's Coupon Scraper

This is a scraper built in Go that finds coupons for Arby's fast food restaurants. This takes advantage of the url formatting Arby's uses to display coupons for when customers need to print them from their email.

How it works:

1. Sign up for Arby's email deals.
2. Wait for a coupon to be emailed to you.
3. Click where it says "Click here for a printable version".
4. You should get a URL like this: http://arbys.fbmta.com/members/ViewMailing.aspx?MailingID=27917361605
5. Remove any query values after the MailingID in the URL.

• Notice that if you increase or decrease the MailingID value you can get a different coupon.
• The scraper works by starting at the MailingID you specify and increases the MailingID until it hits the total requests value.
• Each valid page is saved and the "Offer valid only at:" text and expiration dates are removed be default.

How to use it:

1. go run main.go or go run main.go -id 27917361605

Usage:
-concurrent int
  	Maximum concurrent requests (default 45)
-format bool
