All doujinshi are 10% off the listed price (discount taken off at checkout) till April 30th! There's also a Points/Rewards system where you get 40 Welcome Points and then 1 point for every $1 you spend. Points are good toward future purchases. (though you can use the 40, worth $1.20 on your first order)
Currently the only form of payment I take is Paypal, but if you want to pay by Postal Money Order, email me and we can work something out.
Also be sure to check out: http://www.nekotachi.net/uk ~ she's located (as you may have guessed) in the UK and has lots of nice yaoi manga and some hard to find doujinshi!
