Please note that this item is scheduled to ship via Media Mail.  Pre-Pandemic, Media Mail was reliable, with buyers receiving items typically within two weeks.  However, since the start of the pandemic, it has not been unusual to see delivery times lag well beyond this time period, in some instances, more than a month.  I will gladly upgrade your delivery to either First Class (if the item weighs one pound or less), or US Priority Mail.  Just let me know prior to shipment, and I will charge you for the upgrade.  If you stick with Media Mail, please note that I do not have any control over the delivery time.  I guarantee shipment within one business day after payment, and I deliver the item promptly, with a scan, to the post office.  Once I do that, I am reliant, as are you, on the efficiency of the US Postal Service for delivery.   So please do not send me emails asking, “where is my package?” I don’t know.  I see the same tracking information that you do.  I take pride in my business, but here are the things I have control over: 1) Selling a quality product that is accurately described; 2) Wrapping the package carefully with cardboard and bubble wrap so that it is not damaged during shipment. Yes, the USPS has been known to carelessly handle a package or two, so if the item is damaged during shipment, that is on me; 3) Providing prompt shipment – again, I guarantee shipment within one business day after payment; 4) Providing positive feedback on my buyers – I guarantee this unless you are one of the aforementioned individuals who complain to me about the slow service of the USPS.  You can see the tracking information as well as I can, so if I receive harassing emails from you about the slow delivery of your item, you will not receive a positive rating.  Thank you for your consideration.
