I placed a very large order for light pole globes and received a reasonable price because my order was able to be shipped on pallets. Thank you LBS! There were issues with the production line that was producing my globes, so my order was delayed more than a month. I can understand why my order was delayed, and that the delay was out of Light Bulb Surplus's control. What I cannot accept is that it took me, not LBS, following up on my order to find this out. The responsibility should rest with LBS, not the customer, and then it was up to me to continue to follow up on my order, until it finally shipped.

Thank you for your order and for sharing your honest feedback. We truly appreciate your understanding regarding the production delays, and we're glad the final product met your needs. That said, you are absolutely right—communication during a delay is our responsibility, and we fell short in keeping you updated without requiring you to follow up.

We are currently improving our order tracking and customer notification processes to ensure that any delay, regardless of the cause, is communicated to our customers promptly and proactively. Your input helps us make those improvements, and we value the opportunity to do better.

We appreciate your business and hope to serve you again under smoother circumstances in the future.
