If you have a Black or Silver V4 top and need an upgrade to V5 all you have to do is send it in to us, pay for return shipping with a $1 misc fee (shipping calculates automatically with checkout) OR purchase anything from our site so that shipping is covered, make a note in step 2 when you checkout to ship back your repaired Persei, and we'll send it back with that order
If you have a color (teal, purple, red, etc) Persei, since we don't have any V5 tops in these colors, we would have to ask $10 to change color to Black or Silver, and we'll happily include a free third gen KISS cart to match the Persei on its way out. Be sure to note this in step 2 of checkout
