TadiBrothers has several site codes but the lead choice is the $300 off voucher at the top of this page, which takes $300 off when you spend $1600 on technology and electrical items. That code is best when your cart reaches at least $1600 and you want a straight fixed discount on a mid size to large order.
Small carts under $200: no site code here applies below $200, so you will not get a listed code discount. Browse the sale prices on individual items instead.
$200 to $249: the $20 off orders over $200 code applies once your cart is $200 or more; on a $200 order the code takes $20 off, leaving $180, a $20 saving.
$250 to $349: use the $25 off orders over $250 code once your cart reaches $250. For example, on a $250 order the $25 off code leaves $225, saving $25.
$350 to $374: the $50 off orders over $350 code applies at $350 and up. On a $350 order the $50 code reduces the total to $300, saving $50. There are two similar $50 at $375 style codes; pick the one whose threshold your cart meets.
$375 to $549: the $50 off when you spend $375 code is the clear choice for carts at or above $375 but under $550. On a $375 order the $50 code leaves $325, saving $50.
$550 to $799: the $100 off when you spend $550 code is the next step up, so use that for carts of $550 to $799. On a $550 order the code takes $100 off, leaving $450, saving $100.
$800 to $849: the $125 off orders over $800 code applies at $800 and gives $125 off. On $800 that leaves $675, saving $125.
$850 to $949: choose the $100 off orders over $850 code for carts of $850 and up, unless a better threshold is met. On $850 the $100 code leaves $750, saving $100.
$950 to $999: use the $175 off orders over $950 code once your cart reaches $950. On $950 that leaves $775, saving $175.
$1000 to $1399: the $150 off when you spend $1000 code applies here. On a $1000 order it reduces the total to $850, saving $150.
$1400 to $1599: the $300 off orders over $1400 code gives $300 off at $1400 and up. On $1400 that leaves $1100, saving $300.
$1600 to $1999: use the $300 off when you spend $1600 voucher at the top of this page, which takes $300 off a $1600 order and leaves $1300, saving $300.
$2000 to $2249: the $400 off orders over $2000 code is best once you reach $2000. On $2000 that leaves $1600, saving $400.
$2250 and above: the winter sale $500 off when you spend $2250 code gives the biggest fixed saving for very large carts, taking $500 off a $2250 order and leaving $1750, saving $500.
If you are buying from a sale, any of these codes still require the relevant minimum spend and must be entered at checkout. Several offers state one discount code per order or that they are not compatible with other promotions; use only one code and pick the single code that gives the largest final total reduction for your cart.
Our records show TadiBrothers offered 92 codes in the 12 months to October 2026 and that percentage codes were uncommon, with the biggest percent at 15% and the typical percent code being 15%. Our team ran 88 checkout tests across 88 offers in the 12 months to October 2026, with 12 tests saved as screenshots, so codes arrive often and have been checked at checkout.
Choose the one code that leaves you the lowest final total for the same items. If two codes apply at your cart total, take whichever results in the lower price. Where an offer says not compatible with other promotions or that only one discount code can be used, do not expect to combine codes.
