I'm interested in purchasing one walking aid robot for my personal use and would like to know the total cost, including shipping to my location in Sacramento, California. Could you provide a detailed breakdown of the pricing, including any taxes or additional fees that may apply? Additionally, if there are different shipping options, I'd appreciate it if you could share the estimated delivery times for each. Also, please let me know if there are any warranties or after-sales services offered with the purchase. Looking forward to your prompt response so I can proceed with this order!
