Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
If you are buying these you probably already know what you are in for as I'm sure anyone over the age of 5 in Australia has tried shapes. If you haven't, I'd recommend these BBQ flavour ones and the pizza shapes, both are my favourites.
The great original taste of the Barbecue Shapes is fantastic, I'm so glad they bought it back rather than the 'new' taste. The biscuits are always fresh when opening and stay that way for weeks if the top is wrapped when finished. The only downside is whenever I have them everyone else around me wants some!
