The Sahara is a re-branded Gelert Seabury 6+, so looking for one of those is an idea.
However the Go Outdoors website says the Sahara is available to order. Do you specifically want to get one from a store?
This dealer is selling the Seabury a lot cheaper than the Hi Gear from Go Outdoors, but I can't vouch for them as this is just a quick Google result. TBH the Go Outdoors Sahara appears a bit pricey to me.
