You need to think about what you are after - your first post talks about blowing a number of lbs, and now it sounds like you are attempting to date an lb from Thai Friendly. These are two totally different approaches - do you want to meet lbs for sex or do you want to try and establish a relationship?
You need to get this sorted out, as these are not generally mutually compatible at the same time.
With regards to Victoria's Secret gift certificates - a quick check on Google shows they are ok for use for the on-line shop, but not internationally in other country shops. Also this is not the best way to "woo" an lb. If you want to get a lingerie present, you should buy it for her inThailand - to be sure it fits. Also You are assuming her tastes in lingerie would be the same as your home country - and that might be a mistake.
As mentioned you should read the common answers and questions sections to get yourself up to speed.
