Hi,
I've been reading some of the messages on this forum and am reminded of your situation. Being British but having lived abroad several times I have not only missed but found it extremely difficult to get some items locally. You might not understand the British attraction to Marmite but many overseas countries don't even recognise it as a foodstuff!
So I hope that you will forgive me for posting what is essentially a commercial post but I do so it in the hope that I can provide a service to you and rejoin you with maybe one thing that you may be missing. I help run a site in the UK which sells chilli sauces, many from the US with what I expect are familiar names to you.
If you're interested please take a look at newcomer link: http://www.chilliworld.com [nonactive] or email me if you need any info. We accept all major credit-cards online.
Regards, Robert.
