Katrina,
Priceline have really nice sachets of bath soak for $3- I give myself a couple every year.
Lip balm for dry summer lips, body moisturiser, nail buffers, toe separators for toe polish, hair ties, cute anklet socks (kmart for $2), coffee cup again at kmart for $2, candles, chocolate.
Tanya, great ideas. The lip balm is a great one and I really need to get her a coffee cup.
I was also going to get her a few bags of lollies for when she travels from her place to ours.
