TRC Rehearsal Room 2: where to buy it, v1.0 (2026-09-26)
One recommended vendor per category, one alternate, and the reason the pick wins. Prices are the expected unit prices in costs.csv (before tax and freight). Lead time is order to delivery. "LA pickup" means a counter or showroom within an hour of 2621 Colorado Ave.
Buy the owner items by Wednesday 2026-09-30 if you can. Santa Monica sales tax goes from 10.75% to 11.25% on 2026-10-01 (CDTFA notice L-1037, https://cdtfa.ca.gov/formspubs/L1037.pdf). On the $42,704 of furniture, gear and decor that saves about $214, and Kraft Music's free ground-level shipping on the piano also ends 9/30. The long-lead furniture does not depend on any site measurement, so it can be ordered now.
