I really like Banana Republic for classic work styling, and J Crew for more causal stuff. If you get your email on their mailing lists, they'll regularly (every other day lately) send you 30% or 40% off coupons for use online or in-store. I don't buy their clothing every season ('cause sometimes it's priced ridiculously, at least here in the States), but I get always good ideas from looking through their goods, at least. Although I'm really adoring their clothes for fall this year. Same story with Ann Taylor & LOFT, although I've only shopped at their stores, haven't ordered online. H&M is great for accessories, but it can be difficult to tell what the quality is like if you can't see it in person. Oh, and UNIQLO is amazing for everything - it's like a higher quality H&M, but with an awesome slight Japanese aesthetic.
