ProHealth is running the 30% off code at the top of this page as its main offer. This is the best choice for most shoppers buying full price items, and it beats every other percentage code on the list. The code cannot be combined with other offers, so you will need to choose between it and the other deals available depending on your basket size and what you are buying.
For orders under $100 of full price items. Use the 30% off code. On a $90 order, for example, the code saves you $27 and brings your total to $63. This beats the 10% off code, which would save only $9. The 5% off code saves even less. If you are buying only sale items, check whether the sale markdown alone brings the price lower than 30% off the full price before using the code.
For orders of $100 or more of full price items. You have a choice. The 30% off code still works well: on a $150 order it saves $45, leaving you $105 to pay. The $25 off code for orders over $100 would save $25, bringing the total to $125. The $25 off code for orders over $125 also applies to this basket and saves the same $25. None of these can be combined. The 30% off code wins here and will on any full price order over $50.
For orders of $125 or more of full price items. You still choose between the 30% off code and the fixed price codes. The 30% off code continues to save more as your basket grows. On a $200 order, the 30% off code saves $60, while the $25 off code saves $25. A $300 order shows the difference clearly: the 30% off code saves $90 compared to $25 off.
For the Omega-3 Fish Oil offer. There is a Buy One Get One Free code on Extra Strength Omega-3 Fish Oil 120 softgels. This is separate from the percentage codes and worth checking if that product is in your basket, as the value depends on the usual price. The 30% off code cannot be combined with this offer.
For sale items. The sale page shows markdowns up to 60% off certain products and up to 50% off other sale items. These sales are not codes and do not combine with voucher codes, so you use the sale price as listed. On some sale items the markdown will already exceed 30% off, so compare the final sale price with what the 30% off code would cost on the full price version. If you are buying both full price and sale items, you cannot use a code across the sale items; the code applies only to the full price portion.
For subscription orders. There are two subscription offers: up to 30% off subscription orders and 15% off subscription. The terms state these do not combine with other offers, so if you are starting a subscription, use whichever subscription offer is higher rather than the percentage codes listed above.
For bulk supplements. Up to 30% off selected bulk supplements applies to certain products only. If your bulk item qualifies, compare its sale price to what the 30% off code would cost on the full price.
To choose between the offers that apply to your basket, work out the final price under each one: take the price the offer applies to, apply the discount in order if there is more than one, and compare the totals. Use whichever code or sale leaves you paying the least.
