I am weighing all items that we sell, weight is 11g up to about 600g.
Up to 1 kilo postage rate 1 Royal Mail.
1 kilo and 2 postage rate 2 Royal Mail.
Over 2 kilo will be postage rate 3 TNT.
Should weight be entered as fractions of a kilo?
0.014 and 0.600 entering all this on Excel spreadsheet from Sage 50 Accounts product record.
