Shopper

Shopper is a perl script that finds deals at Tesco on-line shopping site. First you have to specify a list which is a JSON file. Shopper then goes over the list and tries to find best deals.

There are two shopping strategies shopper can use.

  • deal
  • best

Deal will try to find the cheapest stuff. Best will try to find the best stuff under given price. The quality is determined by original price.

When more then one deal is found all the URLs are printed out.

See the list.3dots file for shopping list specification.

Example output

./shopper.pl example_list
