Total Diabetes Supply currently has a 10% off coupon code at the top of this page, the lead offer, and it is best for most purchases of diabetes care products and daily living aids when you want a straightforward percent off at checkout. The coupon code takes 10% off your order on the website only, so use it when you have a normal cart of supplies. The same 10% rate is repeated in other codes lower on the page, but the top coupon is the one shown first.
Small orders under $50. If your cart is small and contains non sale items, use the 10% off coupon code at the top of this page. On a $40 order, for example, the checkout code takes 10% off, which gives a final price of $36 and a saving of $4 (original $40, discount percent 10%, final $36, saving $4). If you are a first time customer and you prefer email offers, signing up to the newsletter may bring future promotions, but it does not replace the immediate 10% code shown here.
Medium orders $50 to $200. The 10% coupon code is usually the best choice for mixed carts that include full price items and sale items that are not already deeply discounted. If your cart contains sale products that already show a markdown, compare the sale price to the price after the 10% code because the code does not apply to sale-only savings unless the product page allows stacking. For ongoing supplies you plan to reorder regularly, consider the 10% subscription option: sign up for subscription and you get 10% off subscriber orders without needing a promo code.
Large orders or bulk test strips. If your cart is made up mainly of sale items such as glucose test strips, the site sale can save more. For example, buying $120 worth of test strips marked down at the advertised top sale rate of 65% off would cost $42 and save $78 (original $120, discount percent 65%, final $42, saving $78). That beats the 10% coupon for high discount sale lines because the sale percentage applies without a code on those items.
Buying pen needles or sale product categories. The up to 53% off pen needles or up to 55% off sale products are valid on selected items with no code. Use those sale prices when the specific item you need is in the sale; if a sale item and a coupon both appear applicable, apply whichever leaves the lower total since the terms here do not state automatic stacking.
Our records show 21 offers listed for Total Diabetes Supply in the 12 months to October 2026, with 7 codes tested by our team in that window. The biggest percentage code in that period was 20% off and the typical code was 10% off, while the biggest sale reached up to 65% off.
When choosing, compare the final totals: use the top 10% off coupon code for regular full price carts or mixed orders where sale lines are minimal, pick the site sale prices for items marked down to 55% to 65% off, and use the 10% subscription deal for repeat orders that qualify. Take whichever option leaves you the lower checkout total.
