mymemory.com discount?

[julian]

I've just taken ages creating an account with MyMemory.com and uploading photos for a photobook, in order to get the promised 75% discount for Photoplus subscribers.
When I key in the code for the discount, it says I'll get a 50% discount (Photoplus promised 75%), but actually only gives a 25% discount - miles short of 75%, so I won't buy the photobooks - or anything else.
Anyone had any better luck?
