NaturalBlonde - there are lots of things if you hunt around on ebay!
More reusable bags that fold into something cute: Strawberry about 50p, Clownfish about 60p, rose bag about 50p
If you hunt you can find things like this deal for 20 of the rose bags to bid on for $12 (nearly £8, which means they come in under 40p each) - looking at what's going to finish soon and seeing the prices, knowing how much the buy it now price is and putting sensible bids and maximum prices in can lead to some real bargains. You can use the ebay filters to set up a maximum price (say $1, about 60p) and free international shipping, sort by time ending soonest and then just see what comes up.
Scarves is another area you can pick up some real bargains - again, doing it the last minute bid method... And there are so many scarves on there that it's not too time consuming if you know that you need say 10 or 20 etc. Last minute list for scarves
Likewise cosmetic bags can be got for less than a dollar - this is a time sorted list...
