FYI-One should ALWAYS include total price information in a selling post. The general accepted practice is to state total price (with all shipping & paypal fees included) or to specify shipping/fee options (i.e. paypal as gift or u pay fees). Also, since USPS Priority (which is the most used method of shipping bats) comes with only $50 insurance its a good ideal to state what insurance comes with the shipping.
Good for you if u can sell it on here but $155 for that 2006 RT SP is a little on the high side. These come in @ $120 tops NIW on SBF Anderson Price Guide (that doesn't include shipping or fees) so I would think $135 tops for these. I got a 2007 RT SP last year from the man himself for less than that. But hey, the price is what it sells for.
