Time travelers have a lot to contend with: What if you show up to ride with Gengis Khan and you’re fresh out of kumiss? Will Leif Eriksson tell you you don’t smell like a warrior? Fortunately, your local Time Travel Mart is there to help, supplying the discerning temponaut with powdered horse milk, Viking odorant, evil robot memory erasers, and 100% non-organic milk, straight from Jupiter Farms!

I particularly like the shoplifters warning sign.
