They don't say anything about getting the tickets at Las Ventas at the Spanish version, the French version or even at the "General Conditions" at the English version. It seems very strange to me that a reseller may has its own booth at the bullring. I'll check it next week and I'll tell you.
As for buying tickets online, Localidades Galicia sell them by phone, fax or e-mail. I guess with Teyci is much easier since you can choose which seat you want and with Localidades Galicia you have to ask them which ones are available.
In either case they don't do any actual selling of the tickets since they are not Las Ventas. They are just resellers so what they actually do is resell tickets they have reserved at Las Ventas for this. Anyway, I'll find out more about them and edit this message then.
