Be very careful with delivery companies and bear in mind that even if you are covered by insurance the small print in the contract puts you in a lose lose position, if you sign for an item as received in good condition because the packing seems undamaged beware, if its broken when you open and youve signed then you lose. If you open it with the courier there, if he will wait which is doubtful, and it is damaged but the packaging isn't then the courier will refuse any claim and point to insufficient packaging. Any claims must be reported with in 24 hours. E-Mail them!!!! Keep a copy.
TNT do not secure anything in their vans so your parcel and the 15 kilo sledge hammer can roll around together while the driver rushes to deliver all his packages and get home for tea.
Post van use TNT as their sub contractor and deliver nothing themselves.
Re-embursments are per kilo and not by value of the item so your light weight dvd or stereo is worth less than the 15 kilo sledge hammer.
I could go on and on but basically read the couriers contract and you will find if you shouldn't sign for anything unless it has been thoroughly inspected, make the driver wait!
Using the royal mail at least if you have a receipt you are covered when sending items.
