Blair Technology Group is showing a $20 off voucher at the top of this page as the main offer, a simple fixed saving that is best for smaller orders where a flat amount beats a small percentage. If you prefer a percentage instead, there is also a 5% off code lower on the page; both codes cannot be used with other offers, so pick one at checkout.
Very small orders, under $400, use the $20 off voucher at the top of this page. A $20 deduction is larger than 5% on any order below $400, so on a $200 order the $20 voucher reduces your total to $180, while the 5% code would reduce it to $190. The codes cannot be combined with sale discounts, so apply the single code that gives the larger reduction.
Around $400, compare the two codes. At $400 the $20 voucher and the 5% code deliver the same saving ($20), so either code works; on a slightly higher basket the 5% code will be better.
Orders over $400, the 5% off code will save more than the $20 voucher. For example on a $600 order the 5% code reduces the total by $30 to $570, while the $20 voucher reduces it to $580, so the percentage code leaves you with the lower total. Remember both codes cannot be used with each other or with other offers.
Buying a refurbished Dell Latitude 7420 or other sale items, use the sale price. The refurbished Latitude shows 18% off as a product level discount, and sale items have up to 16% off elsewhere. Those markdowns apply on the product price on the website and do not require a code. Because the 18% product discount applies directly to the item price, it will usually beat both the $20 voucher and the 5% code on higher priced items; for high ticket sale items the site sale price gives the larger saving.
One year warranty and other non price offers, the 1 year warranty applies to products but does not change cart price. If warranty is important choose the product that includes it, but it does not combine with the voucher rules unless the site states otherwise.
When choosing between the offers, calculate the final totals and take whichever leaves the lower amount to pay. Do not try to stack a code with a sale item because the $20 and 5% codes state they cannot be used with any other offers; pick the single code or accept the site sale price, whichever reduces your total more.
