The Lamson Products page is currently showing the 15% off sitewide promo at the top of the page, available with a checkout code, and it is best for general purchases where you want a simple percentage off everything. The page also lists bundle codes that take 10% when you buy 2, 15% when you buy 3 and 20% when you buy 5, plus a closeout sale with selected items marked down by as much as 78%.
Very small orders, under $50, If you are buying a single low cost item or a small accessory, use the 15% off sitewide code. For example, on a $40 order the sitewide code takes 15% off, so you pay $34 and you save $6. The bundle codes require multiple items so they will not apply.
Two items, If your cart has exactly two qualifying items, compare the two item bundle code and the sitewide code. The two item code takes 10% off the order, but the sitewide 15% code still gives a bigger saving on the same basket. For example, on a $120 order of two items the two item code gives 10% off, leaving $108 (you save $12), while the sitewide 15% code leaves $102 (you save $18), so use the sitewide code.
Three items, The three item bundle code and the sitewide code both take 15% off, and only one coupon may be used per order. If all three items are from the qualifying home and garden range, either the three item code or the sitewide code yields the same result. For example, on a $150 order of three items, 15% off takes $22.50 off, so you pay $127.50 and save $22.50.
Five items or larger multi item buys, If you are buying five qualifying items, use the five item bundle code that takes 20% off, because it beats the 15% sitewide code. For example, on a $250 order of five items the 20% code takes $50 off, leaving $200; the sitewide code would leave $212.50, so the buy five code saves you an extra $12.50.
Closeout sale items, Sale items are already reduced by up to 78% on selected products. A marked down item on closeout can be cheaper than any percentage code on its original price. Because the closeout discount applies to selected products only and the coupon terms do not state they stack, treat the sale price as final unless the site explicitly allows a code on sale items.
When choosing, run the math for your exact basket, then take whichever option leaves the lower total. Remember only one coupon may be used per order, so pick the single code that gives the biggest final price reduction for the items in your cart.
