I thought you might be interested to know that Lulu has two good coupon codes running now which can be used together:
SHIPIT2018 gives free shipping
FWD15 gives a 15% discount.
This means something like the Daygame Nitro hardback is $48, Primal Seduction hardback is $77 and so on. All the other books including my memoir volumes 1, 2 and 4 are also covered by the sale. Just enter the codes in the basket.
