Lanisinoh disposable breast pads are pretty awesome. Saw them in sainsbo's with a 1/3 off and bought a box in preparation, last time it took me forever to find them, I had fountains so they worked for me.
I am an aldi wipe and nappy convert after doing a MN test with DD 2 years ago. She's two and i still buy them for her, good fit, no chemical smell and great wipes for 79p. Aldi is a fair old trek for me, so stock up every month or so, it's worth the trip for me.
Grobags were in TK Maxx for £18 the official brand ones, great price.
Agree with the boots sale/discount shelves, picked a branded travel grobag up for £8 recently. Also got our recent car seat from them, they were the cheapest price, and got tons of points with baby club offers and other things, it was also on 3 for 2 mix and match with other pricey items. Was worth the saving.
Debenhams blue cross sale is coming soon for lingerie. I went last year to be fitted after finishing breast feeding DD and was picking up panache bras for £4-8 it was amazingly cheap, I think I only planned on two new bras and came out with 10 for the same price. They also had lots of nursing bras as well, I plan on getting some new nursing bras next time their sale starts. Though will admit that I am small of back and big of cup, so think they are sizes that aren't as popular in some shades, but I love bright bras, makes me happy knowing I've got something wild underneath :)
