These Elektra prices were from 1970, before WEA was born. Keep in mind, these are just list prices, and list prices only amount to part of the entire pricing picture. It's not by accident that there are several prefix/series for some lists here. There are different wholesale costs for the various prefixes, even though they fall within the same list price. The labels had a number of ways to increase prices: Raising the wholesale without changing the list; moving individual titles from one list to another; raising an entire prefix/series from one list to another, ect. Abbey Road not only came out as a $6.98 list, but the SO prefix always stayed at a higher wholesale cost relative to other prefixes within the list. That is, when this album was released ST, SW, and other Capitol prefixes were $5.98 lists (with different wholesales). Later when they crept up to become $6.98's, the SO titles had their wholesales raised higher than the costs of the others, but remained $6.98's for a while. Then SO prefixes moved to $7.98's before ST, SW. ect. This kind of creeping increase drove us crazy as we used a price averaging system to arrive at prices to sell to retailers.
