Note that on imports, VAT below CHF 5 is not charged. Given a VAT rate of 8% this amounts to a tax free import on all purchases below CHF 62.50, including shipping. Swiss Post will charge an extra CHF 18 on top of VAT as a cash-on-delivery fee if VAT is due. With DHL or UPS you only pay VAT (i.e. no extra fee). Keep that in mind if you order and/or choose your shipping provider. In summary, try to keep your orders below CHF 60 (as a safety margin) if you must use the postal service, and/or choose a different shipping provider for orders above CHF 60.
