I doubt anyone would buy from you versus Tesla. It's quite easy to buy using the inspect element trick for those without CCS charging support, which I assume you may have done since it won't let you order without CCS support.
So my advice is
Returns
Is it possible to return a product?
Vehicle Accessories and Merchandise purchased from the Tesla Shop or a Tesla retail location may be returned within 30 days of receiving the product. Wall Connectors and Mobile Connectors can be returned within 60 days of receiving the product. Opened and unused products have the same return window but are subject to a 15% restocking fee. Outside of warranty concerns, return shipping fees will be deducted from the return credit. Once used, a product is ineligible for return.
