Agreed - as you have to drive past Jekta (the shopping centre) to get off the island, it would be mad not to stop there for a look.
You can buy anything from a hunting rifle to to a pair of skis, I even saw a pair of Asolo 8000m mountaineering boots in one of the outdoor shops.
There's an email address for 'G Max' on this page, they'd be able to tell you for sure what they have;

There is also a shop in town that's a dedicated mountaineering shop, but it would be a bit more awkward to get parked.
