This is not your standard coupon offer, but it is a discount with a difference for La Senza Canada. It's actually a PayPal offer.
If you spend $60 or more there, then pay with Paypal, your Paypal account will be credited with $10 cashback by the 10th of December 2009. The terms say that this deal can be combined with other offers, such as this La Senza couponI posted yesterday.
Some notes from the T&Cs:

If the payment is refunded or cancelled at any time, you are not eligible for the Offer.
