All sales are final. Since all of our products are downloadable files, which cannot unfortunately be protected through the use of serial numbers, all sales are final. We do not offer refunds or exchanges on our digital eCommerce goods.RWtuts offers its products on an as-is basis. We cannot guarantee compatibility with each and every third-party plugin for RapidWeaver. German customers please note: we do not offer VAT invoices, please read our Imprint for more info about that. Some of our products are at an early alpha or beta stage and are therefore missing some core features and can also be buggy. By purchasing a Stack in alpha or beta the customer accepts that he purchases a still broken piece of software and is not eligible for a refund and/or PayPal claim.
