We ship items as they become available. It may be the case that one of your items was delayed or backordered, in which case it may be a little behind the portion of your order that was in-stock.
Additionally, all our tents ship via freight carriers and all accessories will ship separately through Fedex or USPS. This means that even though they may have been shipped around the same time, one or the other may win the race to your house but the other shouldn't be too far behind.
If you're item wasn't on backorder and it has been a long time, you can always reach out to our shipping team and they can look into it further for you.
