If it keeps Royal Mail afloat, do they get massive subsidies?, then it's fine by us. The majority 99.999% goes straight in the recycling bin. Because the limit on the amount of junk mail has been lifted. The extra revenue that Royal Mail are getting could improve the balance sheet if they, the Government, decide to sell off RM.
my very best friend also posts the junk mail back in the post box (like A194). After all, it is unwanted mail, and there is enough to put in the recycle bin already. My VBF's recycle bin was completely full this week.
Post the junk mail back to the sender, most of them provide a return envelope. If everybody did this without ordering or with just the plain empty envelope, it would cost the originators lots of money for nil return.
