The 15% off voucher at the top of this page is the lead offer for Spicewalla, and it is best for most purchases because it takes 15% off all orders site wide. The same 15% saving appears again in a duplicate code further down the page, and there are fallback 10% codes if the 15% code cannot be used. Use the 15% code at checkout to apply the discount on website orders.
Small orders under $25: the 15% off voucher above is usually the best option. On a $20 order, for example, the code takes 15% off, reducing the total from $20 to $17, so you save $3. The free shipping code requires orders over $25, so it does not apply to these baskets. If you are a first time customer and want the newsletter, sign up may send special offers later, but the newsletter itself does not give an immediate guaranteed discount at checkout.
Orders of $25 to $99: you can either use the 15% off voucher or, if your cart is over $25, use the free shipping code to avoid shipping charges. Because the free shipping offer does not state the dollar value of shipping, compare the saved shipping cost to the amount a 15% discount would give you. For example, on a $40 order the 15% voucher reduces $40 by 15% to $34, saving $6. If the shipping fee you would otherwise pay is less than $6, the 15% voucher saves more; if shipping would be more than $6, free shipping may be better for this basket.
Large orders $100 and up: the 15% off voucher above remains the top choice among the listed promo codes. The 10% codes are strictly worse because they take less off the same merchandise, so do not use them if the 15% code works. If you are buying sale items that are already reduced, the site sale has items marked up to 66% off; a sale price that low can beat a general percentage code on that specific item. For sale purchases, compare the sale price to the full price minus 15% and take the lower total for the items you are buying.
Buying sale items: sale items are reduced by up to 66% while stock lasts. That reduction is applied to sale items directly, so if a sale price for the same item is lower than the price after 15% off the full price, the sale price is the better deal for that item.
When choosing between offers, calculate the final total for the same basket using the 15% voucher and using any alternative such as free shipping or a sale price, and pick whichever leaves the lower total. The offers listed do not state any combination rule, so assume each applies on its own unless the site checkout shows otherwise.
