Road cases are an option (amp heads only). This adds some additional cost (weight). We feel this is a secure method to mitigate potential damage that is often caused by careless handling by carriers. You will be provided a return label (pre-paid by the buyer, typically 40-50$) that will be found inside the road case. A $250 deposit is required for the use of the road case which will be returned once the case is back in our possession. 

We accept Paypal (standard Paypal use fee is 3%, NO FEE for personal payment via Paypal), cashiers checks, money orders, personal checks (3 weeks to clear) and bank wire transfers. For international payments we do not accept Paypal.
