I'm interested in purchasing a sample of your product for evaluation. Specifically, I'd like to order a single bottle that contains 400 pills of the combination tablet intended for animal use. The formulation includes key active ingredients beneficial for various treatments, so I'm eager to see how well it performs. For the payment, I can conveniently use either a credit card or PayPal, whichever is easier for you. Please confirm if this is possible and provide me with the total cost, including any shipping fees. Looking forward to your prompt response!
