To our valued customers,

While this time of year typically involves the chance to shop our products on sale, we had to make the tough decision to postpone any promotional pricing in light of supply chain issues, rising costs and several other factors affecting our business as well as our vendors. We know that our Black Friday/ Cyber Monday sales are very popular and we hope to bring them back once these situations stabilize. We appreciate our customers and want to thank you for continuing to choose Advance Adapters.

With sincere thanks- The Advance Adapters Team
