Welcome to the LogicScripts site!
Any scripts purchased will entitle you to free updates as long as there is interest and free support to the best of my ability, also for the free scripts. I will only e-mail you if there are updates/tutorials/user guides available or if new items are added to the store. In return I humbly request that you do not spread/share the non-free scripts. I am a one-man operation scripting these in my spare time. Thanks!
Regarding pricing and tax: For EU citizens LogicScripts does report VAT according to the regulations and VAT rates of your country of residence as a buyer. The prices shown in 'Buy this' (Gumroad store) do not include VAT while the add to cart prices include VAT for EU citizens. Use the currency converter below to get current price in your currency. Keep in mind that PayPal uses a somewhat worse rate in any direction.
