SAMS Scraper API

When in doubt, scrape the freaking HTML. This provides two methods:

var api = require('sams-scraper')(fetch_function);

So in the example case:

var api = require('../index')(require('isomorphic-fetch'));

api.search('pampers diapers', function(result) {
  console.log(result);
}, function(err) {
  console.log(err);
});

The result would be something like this:

[{ image: 'http://scene7.samsclub.com/is/image/samsclub/0003600043839_A?$img_size_233x233$',
    title: 'Huggies Little Snugglers Newborn Kit, N to 10 lbs. (128 ct.)',
    itemId: '513186',
    modelNum: '43850',
    stars: 3.5,
    reviews: 2,
    online: true,
    url: '/sams/huggies-nb-kit-128-count/prod17380209.ip?subscribe=true&xid=subscribe_search',
    freeShippig: true,
    price: 29.98 }, ...]

And:

api.get('/sams/huggies-nb-kit-128-count/prod17380209.ip?subscribe=true&xid=subscribe_search', function(result) {
  console.log(result);
}, function(err) {
  console.log(err);
});

The result is something like this:

{ description: '<p>When it comes to your newborn, only the best will do. These diapers have a&nbsp;GentleAbsorb* Liner with&nbsp;tiny, soft pillows that provide a cushiony layer of protection between your baby&#39;s skin and the mess.

  image: 'http://scene7.samsclub.com/is/image/samsclub/0003600043839_A?$img_size_380x380$' }

Obviously this API is going to break if there are even minor modifications to the HTML on the SAMS site. That being said, it's not all regexs, we do a lot of it by CSS class lookups. So it's not 100% fragile, more like 98.7% fragile.
