Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today both retailers we track have it in stock. Prices barely moved in September 2026, holding around $98.96, so there haven't been real sales lately. Buying today, the lowest price is $98.96 at Optics Planet, which matches the best price we saw in September.
