Q: For items that are Paused, do the consume credits?
A: Paused items still consume product checking credits as your supplier urls are still being checked at the frequency in your settings, but your items are no longer being attempted or calculated to be repriced/updated. So you don't use any repricing credits. That is another reason why items that are not accessible are paused. It helps save you credits; otherwise, the same changes would be calculated and attempted on items that won't update -- it would be a bad cycle.
