Usually every two to three weeks.  It's pretty random.

there will be a new promotion for a WHOLE THREE LISTINGS 19 March - wow

Invitation only: First 3 sales free | 19-23 March

Keep your eye on this page .... someone usually puts up the promotions as soon as they happen  .... they are usually are every 3 weeks.    We might even get another one before the end of March  🙂

Good to know

3 listings on 19 march curraone - for non stores??  where did you find this info please?

My guess is it's similar to what I got a few weeks back. 3 listings where you either pay no fees at all, or have a reduction in the fees. They are strictly invitation only. Meaning, if you didn't get the email, you can't accept the offer.

Here is the link to it http://sellercentre.ebay.com.au/promo/2405 but unless you got the email, you will get the big red message saying Unfortunately, this promotional offer is by invitation only.

thanks and yes you're right.
