Economics on E marketing

Yes economics is part of emarketing or I guess any sort of marketing. We have to know what our economy is doing to know how to serve our clients better in regards to what they are able to spend and if they are willing to spend at the moment in time. So what do you do if the economy is not going well, in respects to e marketing. Start doing offer's online such as groupons excessively bc people will be looking for a deal. Is that what is it about? Or do we keep up the same offers as before? Or is it even about offers? I hope this post makes sense...
