The 15% off storewide voucher at the top of this page is the main offer from StoneSmiths. It is a site wide code that takes 15% off everything and is best for most single orders where you want a straightforward percentage off. Use it if you want the biggest percent off on a typical basket and you are not planning to combine offers.
Small orders under $60, on a $40 order, the 15% off voucher at the top of this page takes 15% off, saving $6 and leaving you to pay $34. The first purchase 10% code applies only to new customers and would save $4 on the same $40, leaving $36, so the 15% code is better for a $40 basket. Note that free shipping requires an order over $60, so a $40 order will not qualify for the free shipping offer.
Orders around the free shipping threshold, if your basket is $60 exactly, the free shipping on orders over $60 will not apply because the threshold is over $60; you need more than $60 to get free shipping. For a $61 order, the 15% code takes $9.15 off, leaving $51.85 and you also meet the free shipping threshold. If you are a new customer, the 10% first purchase code takes $6.10 off a $61 order, leaving $54.90, so the 15% voucher still saves more.
Higher spend orders, on a $200 order, the 15% voucher takes $30 off, leaving $170. The extra 10% code would take $20 off and leave $180, so the 15% code is better. Both of those are site wide percentage codes but per their terms they cannot be combined, so apply the one that gives the larger reduction for your total.
Buying multiple selected devices, the buy one selected device and get one free deal applies when you buy two or more qualifying products. For example, if two selected devices are priced at $80 each (total $160), the BOGO deal makes one free so you pay $80. By comparison the 15% code on $160 gives a $24 saving and leaves you paying $136, so the BOGO deal saves more on qualifying device pairs. The BOGO is for selected products while the percentage codes apply site wide, so check whether the devices are in the selected group before choosing.
First time customers and low spend signups, the 10% off first purchase code is only for new customers; use it if you are new and nothing better applies. The newsletter signup is listed but it is a signup offer and not a main code; mention that only if you want email offers later rather than an immediate discount.

When choosing, run the numbers for your basket: compare the final total after the percentage or fixed deal and take whichever leaves the lower total. Do not combine the site codes because the percentage codes state they cannot be combined; the BOGO applies only to selected products and is a separate deal, so choose the one that gives the larger saving for the same items.
