Mega Depot is running the $50 off coupon code at the top of this page for orders of $1,499 and over. This is your best option for large purchases, and Mega Depot also has tiered codes for smaller baskets, as well as product-specific codes for first time customers buying from certain categories.
On orders under $600: The $5 off code is your only option for orders that don't qualify for the higher thresholds. Use it on a $50 to $599 order, or on the first purchase of certain product ranges like HVAC/R equipment, measuring and layout tools, safety products, networking and wiring, lab and scientific products, or education and teaching supplies if you are a new customer.
On orders of $600 to $999: The $20 off code applies to orders over $599. On a $750 order, for example, this code saves you $20 and leaves you $730 to pay. If you are buying from one of the category-specific ranges above, check whether your order qualifies for a first time customer code instead; the saving is smaller but the code may still work.
On orders of $1,000 to $1,499: The $30 off code kicks in at $999. On a $1,200 order, you save $30, bringing your total to $1,170. This is the best option in this range unless you reach $1,499 and can use the $50 code instead.
On orders of $1,499 and above: The $50 off coupon code at the top of this page gives you a fixed $50 saving. On a $1,500 order, the code brings your cost to $1,450. Use it for any spend at or above the $1,499 minimum.
Buying material handling equipment: The up to 50% off sale on material handling equipment runs until the end of October, and does not require a code. This can be significantly better than the tiered codes, depending on the discount rate applied to the specific items you want. Check the item's markdown before you compare it to a code discount.
Buying in bulk: If you are buying 10 pieces or more of the same item, Mega Depot applies automatic bulk discounts at checkout: 3% off 10 to 24 pieces, 5% off 25 to 49 pieces, and 7% off 50 or more. These discounts cannot combine with promo codes, so compare the discount each method gives before you decide.
As a new customer: Mega Depot offers several first time buyer codes, all worth $5 off a $50 minimum spend. The general first purchase code works on any items at or above $50. Alternatively, if you are buying from hand tools, HVAC/R equipment, measuring and layout tools, safety products, networking and wiring, lab and scientific products, or education and teaching supplies, there is a first purchase code specific to each category, all also requiring $50 spend. Choose the code that matches what you are buying.
To choose between options that apply to your basket, add up what you pay under each offer and pick the one with the lower total. The tiered coupon codes are your simplest choice for general purchases, but compare them to any bulk discount or category sale that might apply to your items. In the 12 months to October 2026, we tracked 158 Mega Depot offers and tested 146 codes at checkout, confirming they work as described. Bigger percentage discounts have appeared, with the largest at 10% off in December 2025, so holding out for a percentage code if you are buying items on sale may pay off.
