I bought quite a few products through big sites like eBay, Amazon, and specialty sites like Paragon Performance, ShoChevyParts.com, Meadowdale Sports, Wildhammer Motorsport, and 404 parts, I had never have any problem with delivery.
I bought the engine bay light kit ($164 - perhaps $20 cheaper than other sites) for my 2023 C8. I did not receive the item and I cannot file any claim with them. I sent them 5 emails before they responded saying nothing they can or will do once the item was shipped.
More likely in the future, I will NOT buy from companies I don't know.
FYI. I should have read the reviews here before purchasing.
