I got some kind of discount then, it was $134. Looks like they're $220 now.
Advance Auto lists a DieHard Platinum AGM Group size 34 for $220, 3 year replacement. They don't seem to discount the DieHards.
Not sure who makes the DieHard these days.

I put the same AGM battery in my 15 Sienna and 11 4R a year ago with no mods. Took a 4 week vacation this summer and left the 4R on a charger. When I hooked it to my smart my smart charger, it ran the diag (always does) and announced it was fully charged before going into trickle mode. Point being, the 4R seems to be keeping it charged without modification.
