Don't get discouraged! Learning to coupon takes time, and even after you've done it for years, there is always something new to learn.
As far as Albertsons goes. Some stores used to hand out doublers, but the policy was changed a few months ago, and they won't give them to you at the store any longer.
If you are worried about coupons that say "Do Not Double," Albertsons now allows you to double those coupons regardless of the wording on the coupon. If you purchase an item for $1.79 with a $1 coupon and a doubler, you will get the item free, but they won't give you an 11 cent bonus overage.
Sometimes word gets out a few days early on Albertsons doublers and this site is a great place to catch wind of it, but overall you aren't going to know about them too far in advance.
The rumors this week are of coupons rounding up to $1 instead of regular doublers, and they are supposed to run a full week. That means that any value under $1 -- whether it be 25 cents or 75 cents, will become a $1 coupon.
As far as your special allergy needs, be sure to check the specialty foods section. Most Albertsons stores have a Kosher/Health Foods section and I've been quite impressed with what they carry. Albertsons seems to carry a lot more gluten-free and specialty foods than a lot of competing stores. However, selection varies from one store to another, so it always pays to look at any Albertsons stores in your region to see how the selection varies.
As far as obtaining coupons for those items, they are out there and HCW is a great place to obtain some of them. In order to trade here, you must graduate from the TNT program, which will show you the ropes. Once you've got five trades under your belt, you can trade with others who have coupons for the items you need.
When I first signed on here, I promised myself I'd give everything a try and discovered much to my surprise that I really loved riding trains. If you try to fill the wishes of others with coupons you are currently throwing into the recycling, you might be surprised to find how many coupons other traders have to pass your way!
