Sam's Club prices vary across the country, so there is no single set price for a cake design from Sam's Club. The Sam's Club website allows users to input their ZIP codes or locations to get lists of relevant local prices for that day.
The type of design required, availability and any relevant special offers also affect on-the-day prices. In general, as of 2015, a half-sheet, decorated, buttercream cake costs somewhere around $20, while a full five-tier wedding cake may cost somewhere in the region of $550. Customers should check their local store's rates by using the Sam's Club online tool or speak to staff in their local store for more details.
