Same here
I have several smaller sites, various niches, traffic from Google, Bing, Yahoo, Facebook ...
28.03. Tuesday, total sessions 1005 -> 36 amazon affiliate clicks; from all sites -> not good

27.03. Monday, 1147 sessions -> 120 clicks
26.03. Sunday, 1238 sessions -> 170 clicks
This Sunday -> Monday drop is regular for my sites and happens all the time, however, when I compare yesterday with other Tuesdays, then:
21.03. Tuesday, 952 sessions -> 66 clicks
14.03. Tuesday, 1184 sessions -> 119 clicks
Obviously, when checking just 'Tuesdays', I have serious drop in affiliate clicks...
I can confirm that today's clicks are down by 60-70%. I'm sure amazon will sort it out by tomorrow, not the first time this happend.
I hope so - yesterday I received Amazon payment for January, so I guess they are busy with sending the money
note: not a singe sale on Amazon today

and my conversion is ~10% these days ... Yes, I like my conversion rate
