Meyer Lemons are so expensive for a few reasons. One, Availability. A regular lemon can be bought anytime of year. Meyer lemons are only available from early winter to the begging of early spring. Two, Shipping. With the Meyer Lemon there is hardly no pith, (the layer between skin and flesh of the fruit) which make these a fragile produce which in return means they are more expensive in the grocery store or at the farmers market.
