Make it very, very obvious that Tracked 24 and Tracked 48 services cannot be dropped off at a regular post office.
It is extremely irritating to drive 5 miles to my nearest main post office only to find out that tracked 24 and tracked 48 services are not accepted there. They need to be dropped off at customer service points and the customer service point next door to the main post office closes at 1PM! You need to make it blindingly obvious that these services are very restricted.
100% agree. Just bought tracked and only after paying did the site tell me I can't take it to my local post office (which is 30 seconds walk from my front door) and instead have to travel half an hour to a service point!
