Don't know about the sales BUT I got over 16 G out of the Shinko S E 890 that I had on the front. Good in all the regimes I've run it in including the Dragon and Moonshine 28 last year on the way to Asheville. AND a couple hundred miles of rain after Asheville on the way to my brothers place North of the Windy City. :Good luck with yer sale huntin!

RIDE SAFE.
That is what I am leaning towards. Glad I checked motorcyclesuperstore best price on Shinko SE890's at 237 total for both while runner up same place is Bridgestone Exedra G701/G702 at 302 in price about same price 302-310 mark as Chapparellracing for the Avon Cobras that lasted me 10K miles.
I want to try something different since Avon Cobras have not impressed me much and although Shinko's may not quite last 10K (guessing 9K), really no bad reviews for the most part. Same as Bridgestone Exedra's maybe lasting 10K or so same as my Avon Cobras with no bad reviews to speak of.
My opinion only, but the overpriced Dunlop Elite III's and Metzeler ME880's pushing that 400 dollar range and more online is tied up into advertising expense since doubt either will last over 12-13K either.
I called up my local Honda dealer and they said good deals right now at 20% discount. I just laughed thinking really? Price was 450 for avon cobras, over 500 for dunlop elite III's, and over 600 for Metzelers. What?? ???
I will call up 1-2 more somewhat local Honda dealers tomorrow morning, but doubt they will even come anywhere close. Just have to find one willing to mount/balance online tires for 40-50 bucks each.
Update: front Avon cobra at 10k looks fine today, holding air and plenty of tread (1-2 more years of riding), so might go cheapest route Shinko SE890 rear tire for 125 bucks and see how it handles/lasts. Might not be 10K more miles like the Avon Cobras, but should get 8-9K and the price is right at 125. I'm not really into super great handling, but longevity, but a car tire on rear is probably not for me.
There is no sense in replacing a perfectly good front tire to match, agree?
Odd though, I checked on Thursday rear tire psi was 42 psi, and today, Sunday, rear tire was still 42 psi so holding air now since warmer temps now? 2 weeks prior mid-April when in the 30's for lows at night, I pumped rear tire up to 46 psi and just almost 2 weeks later on thursday, psi was down to 33 psi (so about 1 psi loss per day before in near 2 weeks but colder out). I doubt it, but maybe 46 psi is just enough inside pressure psi to allow air to escape the 10 pinholes not visible to human eye unless sprayed with soapy water and even then just barely noticeable. Either way, riding rear tire solo for now short 10-20 mile daily trips in next few weeks before I replace rear tire later in May and bringing air pump and gauge and check psi before every short ride for sure.
Sad though, still on 2nd tank of gas since out of storage since April 1st when I noticed the rear flat tire over the winter. Leaning towards cheapest Shinko SE890 for 125 bucks in hopes it lasts 9K close to the Avon Cobras lasting 10K. I'd go car tire on rear since I know it will last 25K miles vs. only 10K on a cycle tire if I rode more miles per year for sure.
The power and weight of the Valk must take a toll on cycle tires since my 250cc scooter still has original tires at 11500 miles but will replace soon due to aging.
