My current one I've had for awhile and it is a bit flaky so I could use an update.If you buy a more expensive wallet, it SHOULD be better made. It'll last a lot longer than a cheap one and should come with a warranty on things like stitching, etc.
if you go through wallets quickly, maybe try for a more expensive one. You can get a nice middle-quality leather wallet for $50-ish from Strandbags or a similar shop that sells ladies' handbags. Might be a bit cheaper than Myer and they often have sales - esp Boxing Day sales or whatever. Just go in after Christmas and pick something up a little cheaper then
I think I'll take your advice and wait until after christmas (although it was 25% off). I certainly don't need a handbag
