Pimms started out as a bottled cocktail. I think the story goes that some oyster bar got so famous for its 'house punch' that they started bottling it for take out.
So. . . Since Pimms is just a pre-mixed cocktail, if you can't buy it simply make your own. Google around and you should find recipes, but from memory something like the following will give good results.
2 parts gin
1 part sweet vermouth
1 part orange liqueur (e.g. Cointreau, Grand Marnier, or Triple Sec or Curacao - best avoid the blue curacao though!)
Just shake it up in a bottle and use it exactly like you'd use Pimms. If you have the above items in your home bar you can basically churn out Pimms to order.
The above recipe can be further improved by adding a little orange bitters. Mind you, if you have orange bitters you probably have access to Pimms.
The strength of Pimms has been gradually reduced over the years, so one advantage of mixing it up yourself is using a nice high-proof gin as the base - hopefully restoring some of the lost kick.
