Atomstack currently lists a 5% off your first order promo code at the top of the page, and that first order code is the lead offer here; it is best for shoppers placing their very first purchase who want a straightforward percent discount on the whole cart. If you are not a first time buyer there is also a general 5% off promo code further down the page and several automatic dollar off deals that kick in at set cart totals.
For very small purchases under $500: use the 5% promo code if this is your first order, or the general 5% code if not. For example, on a $200 order the 5% code takes $10 off, leaving $190, so the code is the only applicable saving here because the automatic discounts start at $500.
For carts of $500 to $999.99: the automatic $40 off orders over $500 is normally superior to 5%. On a $600 order, the automatic $40 off reduces the total to $560, while 5% would save $30 and leave $570, so the $40 off is the better choice for that cart size. The $40 discount is applied automatically at checkout when your order meets the $500 minimum.
For carts of $1,000 to $1,499.99: the $100 off over $1000 is the main automatic saving in this band. On a $1,200 order, $100 off brings the total to $1,100. A 5% code on $1,200 would save $60 and leave $1,140, so the $100 automatic discount wins for most carts above $1,000.
For carts of $1,500 to $1,999.99: the $140 off orders over $1500 applies automatically and usually gives a bigger reduction than 5%. For example, on a $1,600 order $140 off results in $1,460, while 5% would save $80 and leave $1,520, so take the $140 automatic discount when you hit $1,500.
For carts of $2,000 and above: the $230 off over $2000 is the largest listed automatic threshold. On a $2,200 order the $230 discount lowers the total to $1,970, while 5% would save $110 and leave $2,090, so the $230 automatic discount is usually the better pick for high value purchases.
If you are buying marked sale items: the sale states up to 43% off on selected products. That percentage applies only to marked items; compare the final price for that specific product to any cart level automatic discount. For single selected items the sale price often beats a small 5% code.
If you are buying one of the specially discounted parts: the $299 off R30 V2, $119 off FB2 enclosure, and $40 off F2N honeycomb are item specific. If your cart includes those exact products, the listed dollar reductions apply and will often be larger than 5% on those items because they are fixed reductions.

When choosing, compare the end totals and pick the option that leaves you paying less. Automatic dollar off discounts are applied at checkout at the stated minimums; the 5% first order promo is aimed at first purchases and the general 5% promo applies to other orders. There is no stated rule on combining codes with the automatic discounts, so assume only one saving will apply unless the site terms say otherwise; take the single option that creates the lower final price.
