It depends which package you choose. The upper end ones include quite a bit. My fiance and I are doing the Lavish and Opulent package, but there are others. Link to them below.
I think things start to add up if when you want to customize the look of your wedding or add additional decor or entertainment.

Brides: I got the following list of cake flavors from our wedding coordinator, but was a little confused as to whether these are all actually wedding cake flavors.
Some of these (ie cupcake, brownie, macarons) don't seem like it. Is the biscuit a cake flavor, for example?
Rose roses and champagne cream cupcake tower
Red velvet biscuit, strawberry with coconut cream covered
Hazelnut and almond cake with strawberry and hazelnut chocolate cream
Vanilla and caramelized pecan nuts with green apple cream
Blue Berry biscuit with lemon and mascarpone cheese cream
Raspberry, lemon, almond, Irish cream and champagne macarons tower
Mocha and White chocolate brownie with bourbon whiskey cream
Naked red mix berries and roses with vanilla cream
Chocolate/strawberry biscuit with Frangelico liquor and hazelnut cream
Vanilla and orange biscuit with Oreo cookies cream and truffles
