In my opinion, this seller has not supplied enough information; no business name and address, no mention of where the seeds are being shipped from, no quantity of seeds shipped, no prices.
Some countries have very strict import/export laws regarding shipping and receiving seeds, as well as live plant materials and costly phytosanitary certificates as well as other documentation may be needed.
I did an internet search for Galleria Exotic but found nothing for a nursery/seed supplier by that name.
