Using Shapeshift

[LordAMV]

When I am trying to make a transition from LTC to XRP thru Shapeshift, it asks for a refund address.  Would that be the deposit address for my originating account?

That will be your wallet LTC address. In case the payment failled, they know where to find you. Don't pin me on it, since I do not know the amount

Yep, it's your original account in case they need to refund.

Asking this question with some naivete here - but I used Shapeshift to transfer LTC from GDAX to XRP on GateHub.  In the process upon testing the qty of XRP in GateHub, the USD value is nearly 20-25% less than what I spent on the initial purchase of LTC.

Is this common?
