I didn’t see this above my response initially, sorry.
However, this means you had 2000 coins from the pack, and the skin was available for 1900 starting Nov 1, when they modified the store to allow for the sale of individual items previously locked to bundles (this required going to the specific hero in the hero gallery to purchase the item, not directly from the Shop storefront).
And again, if you earned all 360 coins from the first 5.1 weeks of weeklies to add to your 2000 coins from the watchpoint pack, that still doesn’t hit the 2600 needed for the bundle, if that’s what you were aiming for.
