Unfortunately I think there may be legal restrictions on sending bulbs from within the European Union to countries outside such as Turkey (for the present the UK is inside the European Union). For example, I understand that sending bulbs for the UK to the USA requires that the bulbs have a phytosanitary certificate and to get one then the soil where the bulbs have been grown must pass an inspection. Ironically, snowdrops are subject to CITES regulations because of the very large numbers that were being exported from Turkey in the past.
