@gmpirate Absolutely spot-on. Once eBay nabs their 14% cut and you're shelling out at least $8 for shipping, the charm of GWPs isn't what it used to be.
We've gotten pretty good at pegging eBay's going rates for these—Tier 1 GWPs hit around $65 at their peak, then mellow out to $45. Tier 2 dips from $45 to $30, and Tier 3 slides from $30 to $20. Strip away the sentimentality, and we can all agree on which tier they land in.
Personally, I'm in it for "keeps" now—if it's a Tier 2 I like, such as Majisto, it's mine. Flipping for profit, like with Galileo, isn't in my game plan anymore. Still, cashback offers can tempt me into picking up a Tier 2 or 3 I'm not keen on. No cashback, no deal. Another recent temptation has been the cheap rates of Ground Advantage, which save me about $5 on the regular.
But let's be real, holding onto a Tier 2 or 3 isn't a smart play long-term. They don't get much advertisement, so newcomers aren't even aware they exist—which tanks any extra profit you might make on Amazon. This lack of awareness is probably the biggest hurdle, no matter the tier.
