MelodySusie's main offer right now is 12% off your purchase, which beats the store-wide 8% discount for most shoppers. Both deals apply across the board with no code needed, so your decision comes down to which produces the bigger saving in your basket.
For small baskets under CA$100: The 12% off offer will serve you better. On a CA$50 purchase, you save CA$6 compared to CA$4 with the 8% deal—an extra CA$2 in your pocket. This deal rewards quick purchases and small orders.
For baskets over CA$100: The 12% discount continues to give the best result. A CA$200 basket saves CA$24 with the 12% offer versus CA$16 with 8% off, putting you CA$8 ahead. The larger your spend, the more the 12% rate compounds in your favour.
If you're a first time customer: You might also consider signing up to the MelodySusie newsletter before you shop. Many brands sweeten their subscriber welcome offers, so checking for an email signup promotion could unlock an extra deal on top of the main offers listed here—though the newsletter signup itself is not a discount until you receive follow-up promotions.
Since you can only use one offer at checkout, compare the two percentage deals in your basket and apply whichever saves you more. On almost every purchase, the 12% off option will win.
