The majority of us get our yeasts through Mark at marks Home Brew shop, and he is MHB on here. He sells liquid wyeast, which is supplied to him by bigfridge, and he also sells a full range of dried yeast. SO, depending on what kind of yeast you are after, you will find it there. It is on Maitland Rd, islington, right next to the Byrnes surf shop, or ya can call him on 49 696 696. No affilliation, just a happy customer, and you asked.
If you feel like you just want feedback on your IPA, why not sanitise the tap really really well, along with a bottle, and pour it into a bottle straight from the tap, and cap it immediately. It is not the optimal way to do it, but it can be done. Just get a 330mL bottle, so ya can save more IPA for yourself, and send that in. The only reason they request 2 x bottles, is we have a first round comp, where every beer is judged, and feedback given, with the first bottle. The beers that take first place in each of the 9 or 11 categories go into what is called a Best of Show (BOS) round, where experienced judges taste them all side by side and determine which is the best beer at the comp. For example "is this IPA a better example (to style) of an IPA than this dry stout is an example of a dry stout. And is this beglian dubbel a better example of it's style, than the IPA and stout?" etc... until all the judges agree on the best example of style, according to the judging guidelines.
SO, if you feel you only want feedback on how to improve, and dont think it will get through to the BOS round, or even if you do think you will win your category, but dont care about the BOS, where no feedback is given to the brewers, it is decided solely between the judges, then by all means, just put a stubby in. Who knows, you might do well.
Hope that helps

EDIT - If you DO decide to bottle a stubby, keep that puppy stored in the fridge until it is time to get to the drop off points. If you happen to get some bacteria in the beer during the transfer, keeping it cold will prevent the infection becoming too dominant, and thus you will receive good, accurate feedback on how you can improve your IPA the next time around. All the judges are experienced, and most of them are very good brewers, so you will be in good hands.
