Buyers must align the product type with the end-user's needs to optimize costs. For post-operative recovery, a rigid abduction pillow support is required, which is more expensive due to its complex structure. For sports injury prevention (e.g., gym or basketball), a lightweight neoprene compression sleeve is more cost-effective. For chronic pain management (e.g., rotator cuff tendonitis), look for designs with dual-side adjustments to reduce SKU variety, as one size can fit both left and right shoulders, thereby reducing inventory holding costs.
