Match lowest free shipping price

This script will change your price to MATCH the lowest FREE SHIPPING offer in ANY CONDITION on Amazon.com, while ignoring your own price. If there isn’t competition, the script will use your Base Price. This script applies a price floor of Cost or $1, whichever is greater.

You can change the price floor from 1.00 in the script below, if desired.

var item = FILLZ.ITEM.v1;
var f = FILLZ.FILTERS.v1;

// default price
var price = item.base_price;
// price floor
var floor = Math.max(item.cost, 1.00);

// competition filters
var filters = [];
// ignore offers made by me
filters.push(f.seller_id.excludes(FILLZ.SETTINGS.v1.seller_id_for_venue('amazon')));
// free shipping offers only
filters.push(f.shipping.equal_to(0));
// filter offers from amazon.com
var offers = FILLZ.SOURCE.AMAZONUS.v2.offers(filters);

// match if competitors exist after filtering
var lowest = offers.lowest_price_offer();
if (lowest) {
  debug('matching lowest price: '+lowest);
  price = lowest.price;
}

//apply price floor
if (price < floor) price = floor;
return price;
