I need to receive my items by _____ date. Can you make it happen?

No, I can’t. I don’t own the postal services or the shops, so it’s not up to me to promise you a date that you’ll receive your items. For made-to-order products, bear in mind that production time frame estimations given by sellers are generally just estimations. They are subject to delays. Even the most reputable of sellers overshoot promised deadlines for various reasons. This isn’t something within my control. Covid-19 has made things more complicated, particularly in China, and I can only ensure that sellers eventually send out your purchase or try to ask them to cancel your order and give a refund.
