Did Harry Exchange Galleons for Pounds?

 While re-reading (again) the beginning of SS a thought occured to 
me that I didn't recall anyone else bringing up. As I am still a 
relative newbie, I searched the archives to discover whether it had 
discussed before and found nothing. 

 My thought was this. At some point did Harry convert some of his 
wizard money to muggle money? It seems to me that he needed a few 
things from muggle stores and there is no way the Dursley's footed 
the bill. For example, when did he get his trunk? There is no 
mention of him buying one while at diagon alley with Hagred and I 
doubt the Dursley's would have given him even a rotted out one since 
they refused to help in any way with his preparations for attending 
Hogwarts. There is no mention in Cos or PoA of what he wears for 
muggle clothing but is he still wearing Dudley sized clothes under 
his robes? I would think we would be shown his selfconciousness 
about it, especially right after his initial arrival at Hogwarts in 
SS, if he was still wearing clothes that didn't fit. Did he go 
shopping in London before Hagrid put him on the train back to Surrey?
In PoA he has outgrown his robes, does he somehow get some new 
muggle clothes as well? What about pajamas? There is referance to 
the fact that he is still wearing Dudley's rejects in GoF but if he 
did buy some clothes that fit he would probably be smart enough not 
to wear them at the Dursley's house or they would wonder how he paid 
for them? He certainly doesn't want them to know about the money his 
parents left him. I think also, if he was wearing clothes that 
didn't fit, Draco would have used it to taunt him at some point.
What does everyone else think.
