Some of the coral pop ups don't appear for everyone at the the same time. I've had a few and free sounds etc, but then people on OM forums etc haven't had it, but get the same pop up a few weeks later.
The best thing to do is keep logging in once a week or so, I've also been using the extra pence to do a spin or low stakes bj hand, so if my balance is something daft like £10.24 and I'm withdrawing, I'll leave the 24p in and looks for a cheap slot.
I hate the coral site but monitoring wagering is easy in there as you just click on balance and it'll tell you which Jeffers you are working on and how far you are, the slots are usually located under casino.
Betfair free spins are usually for a specific slot so if you head to the wrong one it'll use your own money. You can always check the terms and conditions by going back to the promo section under whichever tab. I usually click eligible games from the t and can kn the offer info and click the slot straight from there, and then keep checking bonus balance if it doesn't pop up " free spins" when opening the slot.
Ladbrokes were giving free spins yesterday when you logged into the casino, I'd had mine earlier in week, you need to click on casino, bingo, vegas or whatever to see all the different promos, just logging won't show freebies on most bookies (coral pops them up automatically which makes up for their shitty site)
I've got two accas going, the dabblebet sign up and the William hill one :) have a million alarms set to remind me to do sequential lays. :)
