I buy this annually. Just for reference purposes, it's currently on the site at $49 without yeast and free shipping. I'll keep yeast out of these numbers:
I bought on the May the 4th be with you discount (15%) for $45.99 down to $39.10 this year with free shipping as part of the sale.
I bought on a 20% discount sale in 2016 $51.51 down to $41.20
I bought on a 15% discount sale in 2015 $51.51 down to $43.78
I bought the extract kit before I converted to AG in 2014 for $45.45.
As you can see, I'm with @voodoo_donut, I rather enjoy this beer. The kit went up $5 but comes with free shipping, whereas if I hadn't bought on a sale this year, I'd have paid the $7.99 shipping so technically it increased, but is still less. It's also still less than it sold for in 2015 and 2016.
