Spring 2018 Coupon

I am just wondering if anyone else taken advantage of the spring coupon to buy a few LOA volumes? I've only been a subscriber to the LOA for 5 or 6 years, so I like to use the coupons to try to fill out my collection as the budget allows. The budget was friendly this spring, so I was able to order:
Le Guin's Orsinia volume, Elmore Leonard's Westerns volume, the first Wendell Berry volume, Melville's Typee, Omoo & Mardi volume, and the volume of Hawthorne's novels. Five volumes for just under $104 seemed like a pretty good deal to me, and this order will probably keep me reading for a while.

What is the code or % you get?

It is 20% off, with the code "spring2018", I think.

I used the coupon to buy the two Norman Mailer volumes, the Wendell Berry volume, the Reconstruction volume, and the special publication, "Shake It Up."

My budget was not supportive this year, but I hope to make a point of planning in future. Apart from the Spring coupon, was there also other(s) at different times of year?

Well I guess I will spend my evening in contemplation of what to buy this year!

>5 elenchus: I think they did a fall coupon last year too. I'm not 100% sure, but I think they did.

I had a similar vague recollection of a Fall coupon.
