SwitchBot currently features the 50% off promo code at the top of the page, the featured voucher you apply at checkout, and it is best if you have a single order with multiple items where halving the total gives the biggest dollar saving. Other active offers include three gift card promotions ($50 off a $550 gift card, $15 off a $250 gift card, $5 off a $125 gift card) and product deals such as the S20 vacuum with a free 4 pack of dust bags, the Blind Tilt Matter combo for $249.99, and the Curtain 3 Matter combo for $245.99. All offers are website only.
Very large carts or multiple items you need now: If your cart total is high, the 50% off promo code is likely best. For example, on a $600 order the code takes 50% off, leaving you to pay $300, so you save $300. Use the promo code at checkout.
Planned future spending of roughly $550: If you want to lock in future spending, buy the $550 gift card with the $50 off code. On a $550 gift card purchase you pay $500 and receive $550 in store credit, saving $50 up front. The gift card terms say gift cards can be used to buy other products later, and codes and gift cards can be used together at checkout.
Planned future spending of roughly $250: The $250 gift card with $15 off means you pay $235 now and get $250 credit, saving $15. This suits you if you do not need the items today but want a small guaranteed saving on later purchases.
Need a $125 value or a small gift: Buy the $125 gift card with $5 off, so you pay $120 and get $125 credit. That is the lowest upfront cost to secure a modest amount of store credit.
Buying one of the marked product deals now: If you want the S20 vacuum, the bundle that adds a free 4 pack of dust bags may be a better immediate value than buying parts separately. If your target is a Blind Tilt Matter combo, its listed price is $249.99; a Curtain 3 Matter combo is $245.99. For a single listed combo purchase these fixed prices can beat the gift card route unless you plan more purchases later.
If you plan to combine saving methods: The gift card terms explicitly allow using discount codes and gift cards together at checkout, so you can buy a discounted gift card and then use it alongside an applicable promo code on a later purchase, subject to each offer term. Each voucher code is valid for one use per customer account.
When choosing between options, work the arithmetic for the same end purchase and pick whichever leaves you paying the least. For immediate large orders use the 50% off promo code; for future purchases or gifts the discounted gift cards give fixed dollar value above what you pay. If both a gift card and a code apply to your purchase, the site allows combining them, so include that in your total and take the route with the lowest final price.
