On the amazon store there used to be 3 shipping options ranging in price and shipping duration. 

The cheapest shipping option was often around $7usd for simple things like memory cards or a hard drive. 

But, amazon have removed the cheapest shipping option so now it is necessary to select the more expensive options. 

I've noticed that amazon had been changing the shipping agent on the cheapest method quite a bit lately.    I thought iparcel had been improving,  but amazon seems to have terminated their relationship sometime ago now. 

Hopefully amazon has plans to reintroduce the cheapest shipping option.....

I thought amazon australia might be a good option now they are operational-- but their pricing is terribly expensive and compares unfavourably to local retail outlets.
