La Senza has a nice little mix and match sale going on right now where you can choose 3 items for $39 (so $13 each). You have choices in the lounge wear and cotton bra categories. I really like their lounge wear and most of the sleep pants are priced around $18.50 regularly so this is a pretty decent sale. They even have some lounge wear that is regular $34.50 for you to choose from. There are lots of mix and match possibilities!
Remember, shipping is free on orders over $89 so see if a couple of friends want to put in an order too and place them together to save on the shipping cost.
