Am I allowed to order something Chametz from Amazon if it will ship after Pesach
If the order is filled on Pesach and your credit card is billed, even if it is shipped only after pesach, the chometz is still owned by you and it is not permitted. However if the credit card is not going to be charged, and the order is not filled for you on Pesach then it would be permitted. Additionally, ordering something on Chol Hamoed Peach would have another issue of doing melacha and preparing on Col Hamoed for after Pesach, and would not be permitted unless not doping so would be considered a davar ha’aved, ( preventing a loss).
