Hmm... but to ordinary users, that page itself is actually a "View 
shopping cart" page (aka basket), they wouldn't imagine it to be an 
order page (as in, if they reload, will order the item twice).  
That's what my client pointed out... so I've got to solve this 
problem, or talk them outta it  :P

Could you elaborate a little?  Do you mean on the basket page itself? 
 The "Buy" button occurs in many types of pages (in this example, 
it's on the flypage), and the last I know, they're already using 
POST.  A little confused here...  TIA for any help!  :)
