How to buy

If you want to buy anything, please get in contact with me first. Don't send any money without having been in contact with me. The risk is big that the amount is wrong.

Most items are unpopulated printed circuit boards but the pictures show the finished product.

All prices are in Swedish currency (SEK ). For currency rates see below.

Postage & packing:

The table below is for items which can be sent as letters, not things which must go as packages. My products are sent with following charges:

Weight [g]	Sweden [SEK]	Europe [SEK]	The rest of the world [SEK]
20	6.00	12.00	12.00
100	12.00	24.00	28.00
250	24.00	48.00	60.00
500	36.00	80.00	90.00
1000	48.00	150.00	180.00
2000	72.00	225.00	270.00

Airmail reach most countries in four to ten days.
If you are ordering heavy items - contact us for current postage rates.
For registered mail add 100 SEK.

Payment:

You have several alternatives:

SWEDISH CUSTOMERS / SVENSKA KUNDER:

Svenska kunder betalar enklast genom Paypal (99% gör det) men plusgiro går också bra.

Postgiro konto 421 22 42-4, P-A Sjöström Elektronikkonsult

OTHER COUNTRIES:

Paypal

Paypal is prefered and 99% of all customers pay that way. You don't have to have a Paypal account since they accept credit cards also.

Don't pay anything, let me bill you first. Good experience of Paypal, it's fast (seconds to minutes), works good. 99% of the business is via Paypal and personally I'll prefer it since it's very fast and you can pay me directly in SEK.

Cash in envelope

Cash in USD and EUR, but only bills/notes (paper money). Send the money in an envelope to my address. If you want, send as registered mail but please avoid this if possible.

Please send to the following address:

Per-Anders Sjöström
Nya Varvsallén 22 C
SE-426 71 Västra Frölunda
Sweden.

Plusgiro

Postal giro account no. 421 22 42-4, P-A Sjöström Elektronikkonsult (add SEK 40 for giro charges).

Bank transfer

Direct to my bank account number (SWIFT):
Nordea Bank Sverige AB
S-105 71 STOCKHOLM
Sweden

BIC (SWIFT-address) NDEASESS Bank Identifier Code
IBAN SE14 3000 0000 0059 0226 1675 International Bank Account Number.
