Check your local shops. Two near me carry reloading supplies, and they get them pretty regularly. Have not seen a small rifle primer for sale online in months, but my local shop got over 100k in a few weeks ago. They're low on everything, and they usually only have 1 or 2 options for each type of primer rather than 4-5, but it's all there.
A few bucks more per case is well worth it for no haz-mat fee, and some free reloading knowledge every time I go in.
