This project is for a Coupon scraper of [login to view URL] Scrape Stores 1. Description 2. Store logo/Screenshot 3. Store URL 4. Average Savings amount (If applicable) Scrape Coupons 1. Coupon Title + actual Coupon Code (If applicable) 2. Store Name 3. Affiliate URL* (Stripped of affiliate ID code and replaced with mine) 4. Expiration Date, Posted date (if applicable) 5. Tags 6. Categories 7. Coupon Type (printable, web, etc) 8. Average savings amount of each coupon (If applicable) 9. Store Image. Saved in database, NOT hot-linked from the site. Will need to have a feature to block certain coupons from being scraped based on certain characters or negative keywords For example, if RTMN is in a coupon, it's an exclusive coupon and would not be used. Will need the option to export it via CSV, XML, TAB Will also need to be able to NOT scrape the same coupon/store/etc twice. This is going to need to crawl from one page to the next, store to store, all the way through their website/s. Please have prior experience with data mining and scrapers and be able to show me examples of them.
