YorkTest offers several codes and deals to bring down the cost of its food sensitivity and allergy tests. The top offer is the featured bundle code that takes 30% off when you purchase a food sensitivity and allergy test together, plus an extra $20 off your order. This is best if you are buying both tests at once.
The key choice comes down to your basket size and which products you are buying.
Buying a food sensitivity and allergy test together: Use the featured bundle code at the top of this page. You get 30% off both tests plus an extra $20 off your order. This combination saves more than any single test code.
Buying a single food allergy test: The $20 off food allergy test code is your best option. It takes $20 straight off the price of that test alone.
Buying the Premium Nutrition Program: Use the code for $20 off the Premium Nutrition Program. No other code applies to this product.
Shopping during the fall sale: The fall sale runs until 31 October 2026 and takes 20% off all food intolerance and allergy tests with free delivery included. Check this against the codes above: on most orders, the 30% bundle code will save you more, but if you are buying a single test only and the fall sale is still running, do the math on your basket. The fall sale gives 20% off the test price plus free delivery; a single $20 off code might save more or less depending on the test's original price.
General purchases and smaller orders: The $20 off storewide code works on any order and can deliver real savings on smaller baskets, though the larger percentage codes are stronger when they apply to your items. Note that the $20 storewide code cannot be combined with other offers.
To pick between the options that fit your basket, compare the total you would pay with each. Take whichever leaves you paying less. The $20 off food allergy test code and the $20 off Premium Nutrition Program code apply to specific products only, so check the terms on the website to make sure your items qualify.
