Is garden soil cheaper than topsoil?

Excuse me, I'm curious about the pricing dynamics between garden soil and topsoil. Could you elaborate on whether garden soil typically comes at a lower cost compared to topsoil? I'm interested in understanding the factors that might influence this price difference, if any. It would be helpful to know if garden soil is a more economical choice for gardening projects or if the benefits of topsoil justify its potentially higher price tag.
