I've just done a simple search for 'this' deal and found several for 9.99 and even more for less (all 6 rolls) BUT no info on width of roll or even the length of each roll so how can you compare/suggest that these are, in fact, deals?
I've just had some delivered. They're 16.5cm wide and about 17cm in diameter (appears to be wound about as tight as most others I've had) - so while not the widest, I'd say they're reasonable value. I've paid more for better ones in the past but, for what they tend to get used for, these look like they'll do the job.
