 - If you're after a bargain on a Pixel device, we suggest buying an "**a**" model, just after the next flagship is released. Discounts are usually available because Google will be trying to clear their stock.
 - Consider price beating options and specials offered at physical stores.
 - Look at online community bargain sites in your country. These can alert you to good sales.

-One metric to determine the strength of a diceware passphrase is how much entropy it has.
