I buy a lot of my underwear sets from eBay as I am a 34a which is difficult to buy for. I like Tesco stockings and save my points and have some great clothes for meals out with clients and shoes from charity shops if you not opposed to second hand clothes which I have pretty much always had to use because of being skint and not making enough yet. Got a brand new Karen Miller dress for ?12 from a charity shop

The odds are good that you are not really an A cup. There are these threads on mumsnet called "bra interventions" where people spread the Good News about the proper way to fit a bra, which is nothing like what M&S do. Google the words "mumsnet good bra guide" and you'll find out what I mean. I used to think that I was a 38 A and therefore bought 36B because I couldn't find them... turns out, I'm a 34 C. I tried out their measuring method because the first time I found out about the Mumsnet Bra Intervention was when someone said on the forum, "Never have we found a true A-cup in one of these threads."

I'm sure true A-cups do exist! But give this a look, anyway. You may be something like a 32 or 30 B or C. The problem is that traditional measuring techniques involve adding a couple of inches to the back and I guess that is because bras used not to be so stretchy. Now, the actual measurement around the rib cage IS the true measurement and then it's a cup size for every inch in difference across the nipples, measured bending over at the waist.

I'm buying stockings at John Lewis, 5? pair, for me better than M&S and definitely better than Primark! Don't buy from Ann Summers, quality is really really bad
Buying condoms on ebay (thanks, Charlotte!  ) - 20? for 150 condoms? Wow! (I'll check out wet wipes as well)
All toiletries (for clients) at poundland
Candles at Primark
Don't buy toys at sexshops, they're very overpriced, this same stuff much cheaper is online

If you search 'paradise4women' on Amazon 4 cheap stockings, I buy them in bulk and they last a lot longer than the Ann summers ones

Same here, on ebay you can get 100 condoms for some 10-15 pounds max, also all kind of eye lashes that come at 10 in a pack for under 2 pounds.

The best find at Primark was some black seam beige hold ups for under 2 pounds I found years ago: I think I bought over 10 pairs, although any other type of stockings was rubbish.  They seem to have decent tights and occasionally cute G strings that match my 34F-G bras I buy at AnnSummers, ebay or rarely designers shops.

The majority of the over priced stuff from LoveHoney can be found on ebay sometimes for a fraction of the price.

If it's an inanimate object, like a dildo, that is fine. If it involves electrics then I'd rather order from something sort of reputable. Lovehoney has great customer service.

Getting a pack of 144 condoms and lube for free from GUM clinic every time I go for my 3 month sexual health check. Telling the staff I was an escort was great because they were supportive, not condescending and helpful. Then they gave me this massive box, haven't bought condoms or lube for a year! 144 free ones every 3 months has been a godsend to my bank balance, can't believe how much money I used to waste just to keep myself safe. Also bulk buying wipes is an amazing way to save money.

Which is good because I am not frugal about anything else work related, I buy all Dior makeup every year and expensive lingerie, not for the punters but so I feel good about myself while at work. I tried the cheaper route and was too uncomfortable. Plus I suck at frugality.

I spend tons on makeup because I love makeup. Like Kay, I feel guilty about getting free condoms. I used to be keen on the freebies but then I went to the little clinic (actually a needle exchange) near me and they had to give me about half the usual because of funding cuts or something. I felt bad about it and haven't gotten free ones since. I'm all about bulk buying on Freedoms, now.
