The 20% off voucher at the top of this page is the lead Mira deal, and it is best for mid to high value orders where a straight percentage saves more than a fixed dollar code. The voucher applies storewide on website orders with the code entered at checkout. If you prefer a fixed discount or are buying a specific bundle, other listed offers may beat it for smaller or bundle purchases.
Small orders under $165. For low value carts, fixed dollar offers often save more. On a $120 order, for example, the 20% off voucher at the top of this page takes 20% off, leaving $96, a saving of $24 (original $120, percent 20% → final $96, saving $24). The $40 off code yields a $40 saving and a final price of $80, so use the $40 off code for this basket. The $15 off code would leave $105, saving $15, which is smaller than both alternatives.
Orders around the $165 free shipping threshold. If your cart is between $165 and $199, factor in free shipping on orders over $165. A $170 order with 20% off becomes $136, saving $34, and also qualifies for free shipping because the qualifying threshold is met before any shipping exclusions are stated here. If you would otherwise pay shipping and the fixed code does not reach $165, the voucher may be more valuable. Check whether shipping is charged before or after a code in checkout if you are close to $165.
Orders over $199. The $50 off storewide code requires a minimum spend over $199, so it competes directly with 20% off on larger carts. On a $300 order, the 20% off voucher at the top of this page takes 20% off, leaving $240, a saving of $60 (original $300, percent 20% → final $240, saving $60). The $50 off code would leave $250, saving $50. For $300, use the 20% code because it saves $60 versus $50.
Buying bundles or multiple items. Automatic bundle deals can be better. If you add four products, the Buy 4, get 25% off automatic discount applies with no code and cannot combine with other deals. For four items totaling $400, the automatic 25% off reduces the total to $300, saving $100 (original $400, percent 25% → final $300, saving $100), which beats the 20% voucher.
Use whichever applicable offer gives the lowest total at checkout. Codes that say they cannot be used with other offers must be used alone, and bundle sales that apply automatically will often give the biggest saving when you meet their item count requirements.
