Bit of an odd one, I have a large Warehouse gift card($1000). More than I'm going to spend in the short term there.
Selling gift cards seems like a bit of a nightmare. I was wondering if the Cheapies hive mind knows something I could buy and sell on Trademe etc to turn this gift card into cash without losing too much $$.

I would say something like PS5/nintendo switch or just try sell the gift card itself on trademe.
