The 30% off full price items promo at the top of this page is the lead Princess Polly offer and it is presented as a code you enter at checkout; use that code when you want 30% off designated items. It is best for shoppers buying full price or specially marked items that the code covers. Other active codes are 22% off your order, a 30% coupon restricted to specific items, and 25% off best selling styles, plus student discounts, a free shipping threshold and a sale with discounts up to 91%.
Under $50, small carts: If your cart is under $50, free shipping does not apply. For a small full price buy of $40, the 30% off full price items code at the top takes 30% off eligible items, reducing $40 to $28, a $12 saving. The 10% newsletter signup on your first order will take 10% off, dropping $40 to $36, a $4 saving, so the 30% code saves more on eligible items. If you are a student and have verified 20% student access, that takes $40 to $32, a $8 saving, which is less than the 30% code but better than the 10% signup.
$50 to higher carts where free shipping matters: If your order is $55, free shipping applies and may affect which offer is best. Apply the 30% code to eligible items to reduce $55 to $38.50, a $16.50 saving; you still keep free shipping because the promotion states free shipping on orders over $50 but the terms do not specify whether the threshold is measured before or after a code, so assume the order reaches $50 before discounts if you started above that. A newsletter 10% cut leaves $49.50 and may drop you below the $50 free shipping threshold if you began at $55; that could add a shipping cost and make the 30% code comparatively better.
Buying sale items: The site sale offers up to 91% off selected items. Sale prices are separate from the 30% full price code which, despite its title, also says in its terms it is valid on sale styles. If a sale item is already marked down 70% to $30 from $100, then the 30% code (if the item is eligible) takes an additional 30% off the $30, leaving $21, a $79 total saving versus original. The 25% best selling styles code only helps when your items are in that best selling set; 25% off a $100 best seller leaves $75.
Student shoppers: If you qualify, the 20% student discount usually gives more savings than the newsletter 10% and may beat the 22% or 25% codes depending on eligibility and which items are covered. Check which student rate applies to your account before choosing.
When choosing between offers, run the math for your exact cart: start with the original price, apply the code or discount in the order the site requires, and take whichever leaves the lower total. If an offer is restricted to selected styles, use that code only on those items. No rules on combining codes are stated, so do not assume two codes can be used together.
