At the end of August, I'll send you the payment link for your first monthly installment: from there, it's 4 monthly payments of €260, and your €50 comes straight back to you with that first payment.
A couple of things to keep in mind:
The deposit is non-refundable if the first payment isn't made by September 1st, 2026.
If you change your mind before August 31st, there's no problem: just talk to me directly and I'll refund your deposit.
