Hi and welcome
As this forum is run by a travel company you can see their list of excusions at
http://www.icmeleronline.com/icmeler_excursions.php together with prices.
All the trips are fully insured.
For a shave there are many places offereing this service, a basic shave starts at about 5TL, if you go for all the extras like a face pack, full shoulder and head massage the price goes up to about 15TL which is good value as the experience lasts about 45 minutes.
If you look at the main
Icmeler forum there are plenty of threads about restaurants and prices for this year, I have only had a bad meal once and I have been going to Icmeler since 2002.
Can't help you with the market as I don't bother going now, but regarding haggling the following was posted by Rami on a a different thread a few years ago
Bartering/haggling in markets
This is expected in most resorts and markets as a general rule- ask the price then offer 1/3 of that price, when the shop owner refuses, offer 40-50% of the original price, gradually increase your price to meet in the middle, if the shop owner won't accept a reasonable offer, walk away - you will often be chased down the road by the trader who will offer you the item at your price or very close to it. If the trader takes the item off you and puts it back on the shelf, you know you have gone below his minimum price, either accept defeat and try a different shop, or increase your price to a mutually agreeable level. You'll know if you are being unreasonable from the person’s body language. Generally don't pay more than 60% of the asking price and never accept the first price offered. Remember you can also barter in a lot of shops (not supermarkets though!) and also in restaurants (before you order the meal though, NOT afterwards.) Here you don't generally argue the price, but more the free extras such as free bread or a free bottle of wine.
