Bubble wrap and then place in a card board box with thermocol shipping. use standard surface shipping if on a budget, if not on a budget, use priority shipping with insurance. Limit pack to 30 LPs. Customs charging you is highly subjective and is also based on luck. Also multiple instances of shipping to the same address can attract attention. USPS is a good option, others are more expensive. If travelling to India, you can hand carry a pack on 30 Lps easily. I've done this several times. However, wrap the LPs in thick paper, that's it (for hand carrying). Remember, most airlines usually allow only 1 cabin bag so its got to be your LPs and your laptop bag at the most. My 2 cents.
