17k sales is really really really small.
No one reads it.
I get the TRP most Sundays and read it as does my other half, and KQ junior when he's home. Our local two supermarkets have 4-5 each on a Sunday and usually you can't get one on a Monday. Readership is likely up to at least twice the 17K unless the other 16,999 are purchased to shred for cat litter, composted and/or used to light fires rather than being read.
It's got a limited readership but good coverage of the English game down through the levels, including reportage down to levels 5 and 6, results and tables down to Level 10 and some Welsh(not just Pro14) and some French. So it's not read by no one. At least three readers and 16,999 buy it to light fires.
