I know, I know, Giab I had a moan to Lol many months ago about the same thing, even did a comparison of other UK reggae mail order shipping charges to show how much more DV's postage was for a single item. In some cases almost triple...but their shipping costs become equal or lower when ordering 3 items or more.
I buy my single items from Juno/SOTU or Jah Waggys as it's much cheaper from them for 1 item.
But still 5 days to NZ man, that's pretty quick
Anyway giab you could sell your house for NZ$1 mill +, buy a new one somewhere else for a reasonable price & still have plenty left over for postage charges aye?
