I accept payments in USD but both payment providers accept multitude of currencies with auto-convert option.
Fees
Paypal: Paypal transaction fee is around 4.99% + $0.49 per transaction.
Stripe: Stripe fee is around 3% + $0.30 per transaction.
Fees will be often slightly higher depending on currency fluctuations and rounding up of values. Please keep extra couple dollars in mind when ordering due to that factor.
